Brown two pounds of lean ground chicken with two cups of chopped onions in a skillet over medium-high heat.
Stir in four teaspoons of chili powder, one teaspoon of cumin, and two teaspoons of salt. Add two small cans of diced tomatoes. Remove from heat and set aside.
Preheat the oven to 350°F and lightly grease the inside of a casserole dish.
Spread a thin layer of cream cheese on a tortilla and place it in the prepared casserole with the cream cheese facing upwards.
Add layers of black beans and the chicken mixture.
Repeat with two more layers of cream cheese, Bisquick tortillas, black beans, and chicken mixture.
Add final flour tortilla and a generous even spread of salsa. Sprinkle with the grated cheese.
Bake for twenty minutes or until heated through.
