Cook up 1 pound of twist pasta according to the package directions, put it in a large bowl, and let it cool. We add in 3 medium diced tomatoes, an 8-ounce package each of cubed Cheddar and mozzarella cheeses (or cube em yourself), 6 sliced scallions, and a 3-ounce package of sliced pepperoni. Pour a vinaigrette dressing over it made by combining 3/4 cup vegetable oil, 1/2 cup red wine vinegar, 2/3 cup grated Parmesan cheese, 2 teaspoons dried oregano, and a bit of garlic powder, salt and black pepper. Give it a good toss, cover it, pop it in the fridge to chill, and its ready for the table.
