Taste the earthy flavors of the Mediterranean in every bite of this colorful summer salad. Tangy feta cheese, fresh mushrooms, tomatoes, onions, bell peppers and olives are tossed with spicy pepperoni and macaroni in an herb-infused vinaigrette.
In a large bowl, whisk together olive oil, vinegar, garlic powder, basil, oregano, black pepper, and sugar. Add cooked pasta, mushrooms, tomatoes, red peppers, feta cheese, green onions, olives, and pepperoni. Toss until evenly coated. Cover, and chill 2 hours or overnight.
