I tried Tom Brady's vegan meal-kit delivery service - and learned I don't have what it takes to cook for the world's greatest quarterback

Tom Brady, 40, is the greatest quarterback in football history, according to the NFL, sports bloggers, and this New England-bred sports fan. The five-time Super Bowl champ didn't reach peak condition at an age when most players have already retired by eating chips and dip.

Brady owes his longevity to an intense diet and workout plan, which the GOAT ("greatest of all time") touts in his new book "The TB12 Method." Vegetables make up 80% of what he and his supermodel-wife Gisele Bündchen eat, along with whole grains, nuts, and lean meats.

In 2016, Purple Carrot, a meal-kit delivery service that serves 100% plant-based foods for a vegan diet, partnered with Brady to bring meals based on the way he eats to customers. Using the guidelines laid out in his book, TB12 Performance Meals deliver aim to "help athletes and active individuals stay at their peak" - just like the GOAT. (Though Brady is not a vegan.)

For $78 a week, subscribers receive three meals with two servings of each.

I recently tried the TB12 Performance Meals for two weeks. Here's what it was like.
