Cook the pasta to al dente based on the package instructions and drain.
While the pasta is cooking, heat the olive oil in a large skillet over medium high heat. Then add in the diced onions and cook for 3-5 minutes until the onions are tender and translucent. Then add in the minced garlic and cook for 1 minute until the garlic is aromatic.
Then add in the marinara sauce, sliced pepperonis, water and Italian seasoning. Stir until well combined. Bring the mixture to a low boil. Cover and let the mixture simmer for 8-10 minutes.
Then stir in the cooked pasta, 1 1/2 cup of the mozzarella cheese and the parmesan cheese. Turn off the heat and cover the skillet to allow the meal to melt the cheese.
Then top the meal with the remaining shredded mozzarella cheese and allow for it to melt.
Serve topped with chopped parsley and enjoy!
