In a large skillet over medium heat, add the vegetable oil and diced peppers. Sauté for 2 minutes or until the peppers are tender.
1 teaspoon vegetable oil, 1/2 cup diced bell peppers
Stir in the minced garlic and continue to sauté for about 30 seconds.
1 teaspoon minced garlic
Add the sauce and water, stir, and cover.
1 15-ounce can pizza sauce, 3 1/2 cups water
Once the mixture has come to a boil, add the spaghetti noodles and stir.
8 ounces uncooked spaghetti noodles
Keeping the skillet covered, cook the noodles until they are soft, stirring every couple minutes so the noodles do not stick together. This will take about 20 minutes (majority of the moisture will have been soaked up by the noodles).
Remove the lid and stir in the Parmesan cheese, mushrooms and most of the pepperoni and olives (save some for garnish). Cook on low for a minute or until the mix-ins are heated through.
2 tablespoons grated Parmesan cheese, 1 4-ounce can mushrooms, 4 ounces sliced pepperoni, 1 2.25-ounce can sliced black olives
Turn the burner on low and sprinkle the mozzarella cheese on top. Top with the remaining pepperoni and olives. Cover the skillet for 2 minutes to melt the cheese.
1 cup shredded mozzarella cheese
Sprinkle with fresh basil and serve while warm!
2 tablespoons fresh basil
