Brush both sides of the chicken with olive oil and sprinkle with the taco seasoning.

Place the chicken in a casserole dish and bake in a 400 degree oven for 25 minutes.

Note: Increase bake time if using regular cut (not thin cut) chicken breasts,

As the chicken bakes, cook the chorizo in a skillet over medium heat for 5 to 8 minutes, breaking it apart as it cooks. Drain on paper towels to remove excess grease.

When the chicken is done, top the chicken with the cooked chorizo and pour the queso over top. Bake an additional 5 minutes. Serve with tomatoes and cilantro over top if desired.

Note: This is very good if served with warm tortillas and/or tortilla chips.
