Cook the Pasta: Boil the pasta according to the package instructions until al dente. Drain and let it cool. To prevent sticking, toss with 1 teaspoon of olive oil and spread it out on a baking sheet.

Chop the Ingredients: While the pasta cools, dice the bell peppers, cut the tomatoes in half, slice the mozzarella, and chop the salami and pepperoni.
1 red bell pepper, 1 green bell pepper, 4 ounces salami, 4 ounces pepperoni, 8 ounces mozzarella cheese, 1 pint grape tomatoes
Mix Everything Together: In a large mixing bowl, combine the cooled pasta, bell peppers, olives, tomatoes, mozzarella, salami, and pepperoni.

Add the Dressing: Pour in the Italian dressing and toss everything together until well coated.

Chill the Salad: Cover and refrigerate for at least one hour (or ideally 2-4 hours) before serving. This allows the flavors to fully blend for the best taste.
