Preheat your oven to 375°F (190°C).
Poach the chicken breast in simmering water for 12-15 minutes until fully cooked, then shred it using two forks.
In a small mixing bowl, whisk together the tomato sauce, chili powder, ground cumin, garlic powder, onion powder, sea salt, and black pepper to create the red chili sauce.
In a separate bowl, combine the shredded chicken with the diced green chiles and 2 tablespoons of the prepared red chili sauce.
Warm the corn tortillas in a dry skillet over medium heat for 30 seconds per side until they are soft and pliable.
Divide the chicken and chile mixture evenly between the two tortillas, roll them up tightly, and place them seam-side down in a small oven-safe baking dish.
Pour the remaining red chili sauce over the top of the rolled tortillas and sprinkle with the shredded sharp cheddar cheese.
Bake for 15 minutes until the sauce is bubbling and the cheese has melted into a golden crust.
Garnish with freshly chopped cilantro and serve immediately while hot.
