Preheat your oven to 375°F.
Heat 1 tsp extra virgin olive oil in a skillet over medium heat and sauté 0.25 cup yellow onion and 0.25 cup bell pepper until they are soft and fragrant.
Add 4 oz thinly sliced chicken breast to the skillet and season with 0.25 tsp sea salt, 0.25 tsp black pepper, and half of the ground cumin and garlic powder.
Cook the chicken until it is opaque and fully cooked through, then remove from the heat and shred the meat using two forks.
In a small bowl, whisk 0.5 cup tomato puree with 1 tsp chili powder and the remaining cumin and garlic powder to create a clean red chili sauce.
Warm 2 medium corn tortillas in a dry pan for 10 seconds per side to make them pliable and prevent cracking.
Fill each tortilla with the shredded chicken and pepper mixture, roll them tightly, and place them seam-side down in a small baking dish.
Pour the red chili sauce evenly over the tortillas and top with 0.5 oz shredded sharp cheddar cheese.
Bake for 15 minutes until the sauce is bubbling and the cheese has melted into a golden crust.
Garnish with 1 tbsp fresh cilantro before serving.
