Heat a large skillet over medium-heat. Add 1 tbsp of oil, the chicken, and a chopped onion.
Season with salt, pepper, chili powder, cumin, and dried cilantro.
Once the chicken is pretty much cooked through, add the minced garlic, elbow macaroni, chicken broth, Rotel, and a can of tomato sauce.
Stir everything together well and bring to a quick boil.
Once you see bubbles, turn the heat down to medium low. Cover with a lid and cook for about 12 minutes or until the pasta is cooked. Stir at least once about half way through to keep the pasta from sticking to the skillet.
Finally, add the shredded cheese and milk, stir, and let sit until the cheese is melted. Serve and top with fresh cilantro. Enjoy!
