There's the pork patty, barbecue sauce, onions, and pickles.
But a key differentiation puts Burger King's version miles ahead of the McDonald's item, notes Scott Hume at Burger Business.
Burger King's sandwich costs about $1, compared with $3 for a McRib.
"The BBQ Rib, described 'juicy boneless rib patty, freshly cut onions, crisp pickles, a sweet and spicy BBQ Sauce and all served on a on a warm toasted sesame bun,' is a serious challenger to the Dollar Menu & More and the McRib," Hume writes.
With customers watching every dollar, the price differentiation is an important one.
Like the McRib, the BBQ Rib sandwich will be served for a limited time.
