Preheat your oven to 375°F (190°C).
In a large skillet over medium heat, add the olive oil, diced onion, and diced bell pepper.
Sauté the vegetables for 5-7 minutes until they are tender and the onions are translucent.
Add the shredded chicken breast, sea salt, and ground cumin to the skillet, stirring for 2 minutes until the chicken is well-seasoned and hot.
Pour about 2 tablespoons of the enchilada sauce into the bottom of a small baking dish and spread it evenly.
Warm the corn tortillas in a dry pan for 30 seconds per side until they are soft and pliable.
Lay a tortilla flat, place half of the chicken and vegetable mixture in the center, and roll it up tightly.
Place the rolled tortilla seam-side down in the baking dish and repeat with the second tortilla.
Pour the remaining enchilada sauce over the tortillas and top evenly with the shredded cheddar cheese.
Bake for 15-20 minutes until the sauce is bubbling and the cheese has melted into a golden crust.
Remove from the oven and garnish with fresh cilantro before serving.
