To prepare a tex mex skillet pasta pie pasta recipe, you'll first need to prepare the pasta. You can use any type of pasta, as long as it hasn't been thawed. If you want to use fettuccine, use the same method as for the spaghetti and meatballs. Heat the olive oil over medium-high heat. Add the garlic and saute until fragrant, about 1 minute. Stir in the cheese and cook, stirring, until it's melted, 1 to 2 minutes. Remove the skillet from the heat and add the cooked pasta to it. Toss to coat it evenly with the sauce.
