Heat a nonstick skillet and an enameled cast iron skillet over medium-high heat. Season the chicken breasts with the Mexican spice blend and the salt to taste. Put the oil in the cast iron skillet. Add the chorizo to the nonstick skillet and the chicken to the cast iron skillet.
Break the chorizo up with a spatula as it cooks, then add the peppers and onions. Flip the chicken after five minutes and set a timer for another five minutes. After flipping the chicken, add the cream cheese to the chorizo mixture and stir until it melts, then stir in the cream.
When the chicken has cooked for five minutes on both sides, turn off the heat on both skillets and pour the chorizo sauce over the chicken. Top with the cheese and bake at 350 for 10 minutes. Remove from the oven and serve.
