DENVER (AP) — Chipotle Mexican Grill is testing a new burrito filler that it hopes will appeal to vegetarians and vegans.

Sofritas — made with shredded organic tofu braised with chipotle chilis, roasted poblanos and spices — will be tested at seven San Francisco Bay area restaurants starting Feb. 12. It also will be available in tacos, burrito bowls and salads.

Denver-based Chipotle previously tested a "Garden Blend" vegetarian item but wasn't satisfied with it and started developing Sofritas.
