Creating Salsa Fresca Baked Chicken is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Salsa: In a mixing bowl, combine diced tomatoes, chopped onion, cilantro, jalapeño (if using), minced garlic, lime juice, cumin, chili powder, salt, and pepper. Mix well and set aside.
3. Prepare the Chicken: Place the chicken breasts in a baking dish. Drizzle with olive oil and season with salt, pepper, cumin, and chili powder on both sides.
4. Top with Salsa: Spoon the prepared salsa mixture evenly over each chicken breast, ensuring they are well covered.
5. Add Cheese: Sprinkle shredded cheese on top of the salsa-covered chicken.
6. Bake: Place the baking dish in the preheated oven and bake for 35-40 minutes or until the chicken is cooked through and the internal temperature reaches 165°F (75°C).
7. Cool: Remove the dish from the oven and let it rest for 5-10 minutes before serving to allow the juices to redistribute.
8. Serve: Garnish with additional cilantro and lime wedges if desired.
