Preheat the oven to 400F and and ovenproof skillet to medium-high with a drizzle of olive oil. Combine all the spices in a small bowl.
When the skillet is hot, add the chicken in 1 layer with a sprinkle of the seasoning blend. Let the chicken cook for 1-2 minutes, then flip when chicken is brown. Brown on the second side, then remove to a plate. Brown the chicken in multiple batches if you need to.
Add the vegetables to the hot skillet, and turn off the heat. Sprinkle the veggies with a bit more seasoning blend. Arrange the browned chicken on top of the vegetables, and pour the salsa and tomato sauce on top.
Bake the skillet at 400F for 15-20 minutes until the chicken is cooked through and the sauce is bubbly. Serve with rice, salad, or any way you like.
Enjoy!
