FIRST STEP: PREPARE THE CHICKEN

1. Season the Chicken: Begin by seasoning the chicken breasts with cumin, chili powder, garlic powder, paprika, salt, and pepper. Drizzle the chicken with lime juice and rub the spices into the meat to ensure it’s well-coated. Let it sit for about 10 minutes to absorb the flavors.
2. Cook the Chicken: Heat the olive oil in a large skillet over medium-high heat. Once hot, add the chicken breasts to the pan and cook for about 6-7 minutes on each side, or until the chicken is golden brown and fully cooked through. The internal temperature should reach 165°F (74°C). Once the chicken is cooked, remove it from the skillet and set it aside to rest.
3. Slice the Chicken: After the chicken has rested for a few minutes, slice it into thin strips or bite-sized pieces, depending on your preference. Set aside for the cheese sauce.

SECOND STEP: MAKE THE CHEESE SAUCE

1. Melt the Butter: In the same skillet, melt the butter over medium heat, using the residual flavor from the chicken to add richness to the sauce.
2. Whisk in the Flour: Once the butter has melted, whisk in the flour and cook for about 1-2 minutes, until the mixture turns a light golden color. This will help thicken the sauce.
3. Add the Milk: Gradually add the milk, whisking constantly to prevent lumps from forming. Continue whisking until the mixture thickens, about 3-4 minutes.
4. Add the Cheeses: Reduce the heat to low and stir in the shredded cheddar and mozzarella cheeses. Keep stirring until the cheese has melted and the sauce is smooth and creamy.
5. Season the Sauce: Add taco seasoning, hot sauce (if using), cumin, salt, and pepper to taste. Adjust the seasoning according to your preference, making sure the sauce is flavorful but not too spicy unless you enjoy heat.

THIRD STEP: COMBINE CHICKEN AND CHEESE SAUCE

1. Add the Chicken: Once the cheese sauce is ready, add the sliced chicken to the skillet. Stir to coat the chicken in the cheese sauce, making sure it’s evenly distributed.
2. Simmer the Chicken: Let the chicken and sauce simmer together for about 3-4 minutes, allowing the flavors to meld and the chicken to heat through.

FINAL STEP: SERVE AND GARNISH

1. Serve the Dish: Spoon the cheesy chicken mixture onto plates or into bowls. You can serve it on its own or with sides such as Mexican rice, refried beans, or a fresh salad.
2. Garnish: Top with fresh cilantro, sliced jalapeños, lime wedges, and a dollop of sour cream for added flavor and color. Serve immediately, and enjoy the creamy, cheesy goodness!
