Start by boiling a large pot of salted water. Once boiling, add the medium pasta shells and cook according to package instructions until al dente. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Once hot, add the chopped onion and sauté for about 3-4 minutes, or until translucent.
Add the lean ground turkey (or beef) to the skillet. Use your wooden spoon to break it apart. Cook until browned and no longer pink, about 5-7 minutes.
Stir in the minced garlic and cook for another minute until fragrant.
Pour in the tomato sauce and water, stirring to combine. Add the ground chili powder, cumin, smoked paprika, oregano, salt, and black pepper. Mix well and let it simmer for about 5 minutes.
Fold in the drained pasta shells and mild green chiles. Sprinkle in the shredded cheese and give everything a good stir until the cheese melts and coats the pasta and meat.
Spoon the Taco Pasta into bowls and top with your favorite toppings like sour cream, sliced green onions, or avocado. Get ready to dig in!
