Add in marinara sauce, cooked meatballs, and cooked pasta. Stir to combine.

Notes
Pasta: I like to use a tubular pasta like rigatoni, penne, or ziti in this recipe.
Pasta sauce: I like to cook onions and garlic to add to my sauce because it adds a nice layer of extra flavor to the pasta. If you have homemade sauce, feel free to sub it for the jarred kind.
Meatballs: I use homemade meatballs if I have them. Otherwise, frozen meatballs (that have been cooked) will work just fine.
Mozzarella: You can use shredded mozzarella cheese if you prefer.
