We make $340,000 a year and shop at Costco twice a month. Here's what we buy and how we use it.

• My husband and I make about $340,000 a year, and we shop for two on our twice-monthly Costco trips.
• On this trip, we spent $275 on essentials like tofu, avocados, protein bars, and coconut water.

My husband and I are DINKs — dual income, no kids — in New Jersey who make about $340,000 a year.

I'm a freelance copywriter and travel writer who works on contracts with several advertising agencies. No two months are the same, but my income is pretty steady.

My husband works as the vice president of an investment bank in New York and typically clocks in 50 to 60 hours a week.

Our work lives are bridled with uncertain work hours, but we are creatures of habit — and shopping at Costco is one of them. After all, the wholesale retailer helps us save money on groceries and essentials.

We go twice a month and typically spend about $200 to $300 per trip. I'd say our habits are pretty on par with the average shopper — Costco's typical customer spends $100 per trip and visits the retailer twice a month.

Here's what we usually fill our cart with.

Tofu is our go-to protein source

As vegetarians, we add tofu to at least one meal a day. Sometimes we put it in a veggie wrap or biryani (mixed rice dish). Other times, we just season it and toss it in the air fryer.

Nasoya's Tofu comes in a pack of four 18-ounce blocks, for just under $7 — one of the best deals we've seen at grocery stores.

We stock up on produce like vine tomatoes, sweet onions, baby spinach, and avocadoes

At $8 a box, vine tomatoes are a Costco staple for us because they're more aromatic and flavorful than other tomato varieties we've tried.

We especially love them baked on a pizza or roasted for quinoa bowls or a Sante Fe salad.

We also cook with Oso sweet onions a lot since they have a delicate flavor when sautéed and they caramelize pretty quickly. We usually get a large bag for $4.50

Baby spinach is another produce-aisle staple, especially now that we have gym memberships and make green juice before working out.

Our juice usually contains spinach, kale, protein powder, and any superfoods we can get our hands on, like hemp seeds and microgreens.

Lastly, we stock up on avocados to turn into dips because we love any dish that takes minimal effort. We especially love making guacamole with kale and black beans.

We pay $6 for six avocados at Costco, which feels like a steal.

Pecans are a key part of our morning routines

While growing up in India, my partner and I developed the habit of dipping cookies into our morning coffee.

Instead of dipping cookies, we now just pair our coffee with pecans. Unusual as it sounds, a crunchy pecan followed by a sip of hot coffee tastes great.

A 2-pound bag of Kirkland Signature raw pecan halves usually lasts us a month and costs $11.

Baguettes and crepes are hosting essentials for us

As a couple without children, we make sure to fill our weekends with a lot of socializing. We love having friends over, so we keep quick bites on hand for movie marathons or game nights.

Baguettes are our main social snack, and we can get a sizable two-pack for $6 at Costco. We slice them and top each piece with avocados, tomatoes, and cheese. Then, we bake our rounds until they're golden brown.

We also stock up on St Mitchel chocolate French crepes so we can make our friends (our ourselves) a quick dessert.

We pair crepes with diced strawberries and low-fat cream. At Costco, we usually pay $8 for 20 crepes.

Stonefire naan helps sort out our Indian food cravings

My partner and I usually cook Indian fare on Wednesdays and Sundays.

It can be time-consuming since every gravy needs a lot of ingredients, so we cut corners with our naan, the main accompaniment.

Instead of making it from scratch, we buy packs of 18 Stonefire mini naans at Costco for just $6.

Sometimes we use these naans as the base for cheesy pizzas, too.

Tropical's Queso de Frier cheese can make any meal delicious

I love this white cheese solely because it turns out crispy on the outside and soft on the inside when you air-fry it. No breading required.

It goes well with a chili-lemon seasoning and can be eaten in a veggie bowl or as a stand-alone snack.

Two 16-ounce packs of Tropical's Queso de Frier cost us $9.

Coconut water is always in our badminton kit

Harmless Harvest coconut water has electrolytes and provides us a much-needed boost before our weekly badminton game.

It also has a refreshingly sweet taste. A pack of six 14-ounce bottles cost us $21.

Simply Protein bars are perfect for midday cravings

Protein bars usually make me feel bloated, but I like how light the Simply Protein bars are with their rice texture.

I usually buy a box of the chocolate-peanut-butter flavor — the lemon ones aren't for me. We got 15 bars for $14 on this Costco trip because there was a $4 discount available.

We usually check out Costco's homeware aisles, too

We rely on Costco for kitchenware and appliances as we trust the quality of what the chain sells immensely. Sometimes we even pick up decor items.

On this trip, we got a faux-wicker basket for $20. I'm confident it'll last us years.

We have natural wicker baskets in the living rooms for our throws, but faux wicker seems engineered to handle the damp kitchen napkins better.

Overall, we spent $275 on this Costco trip

On this Costco run, our bill came to $275.75.

In addition to the items above, we bought other items, including large bags of potato chips, a pack of tiramisu dessert cups, Neutrogena Rainbath shower wash, and a pack of Super Nature Potent Aloe shampoo and conditioner.

The Super Nature set cost us $45 and was the most expensive item on the list — but we're taking extra care of our hair and didn't mind the price.

This haul will last us about 15 days — then we'll have to head back to Costco for another shopping trip.
