If you choose to use cream cheese, add it as first layer on the baking dish. I skipped cream cheese.
Add refried beans and spread it evenly on the casserole baking dish.
Add a layer of black beans. You can add as much or as little you prefer according to your taste preference. Canned black beans should be drained and rinsed before you use.
Add a layer of corn. If using canned corn, drain it completely and use.
Add half the quantity of salsa and spread evenly.
Sprinkle little salt, pepper and taco seasoning.
Place seared chicken breast on top of salsa.
Top each chicken breast with remaining salsa. Spread evenly all over the breast.
