Saute the onion and garlic in olive oil until softened, about 2-3 minutes.
Stir in the chicken, beans, some salt and pepper, and heat for 1-2 minutes. For the chicken, I use my Instant Pot Shredded Chicken Breasts, but any cooked chicken will work. Rotisserie chicken would work great here.
To assemble the enchiladas, fill a tortilla with a few tablespoons of the chicken/bean mix, top with 2-3 tablespoons of grated cheddar, and roll. Amounts of filling and cheese will vary, depending on the size of your tortillas. See step-by-step photos above for the rolling process with flour tortillas.
Repeat this until all of the filling is used. Don't overfill your tortillas or they will break.
Oil a 9 x 13 baking dish.
Spread 1/2 cup of the enchilada sauce onto the bottom of the dish.
Place the rolled and filled tortillas, seam side down, into the dish.
Top with the rest of the enchilada sauce, grated cheddar, and olives.
Bake for 15-18 minutes, uncovered, or until bubbly and melted.
Sprinkle the top with fresh cilantro and scallions.
