I replaced the tomatoes with 1 lb chicken breasts cooked in Ro*Tel's Mexican Tomatoes with Lime Juice & Cilantro according to the can's directions. It is enough chicken for 2 triple-decker quesadillas. The layers go beans, chicken, sour cream, cheese, then avacado. That way the chicken is stuck to the beans when you go to flip. I recommend heating the refried beans to make them easier to spread. Also, you need a really big/wide spatula to have any hope of flipping without a total mess.
