Boil chicken breast until fully cooked, then shred using two forks.
Heat olive oil in a pan, sauté diced onion and garlic paste, then stir in cumin powder, paprika, tomato sauce, and salt.
Mix shredded chicken with half of the prepared sauce.
Spoon chicken filling into tortillas, roll tightly, and arrange seam-side down in a baking dish.
Pour remaining sauce over top, cover with shredded cheddar cheese, and bake at 190°C for 20 minutes.
