This pasta salad is always a hit at family picnics. I usually follow my recipe, but if I don't have the exact ingredients, it's very easy to substitute. Make it your own by using your favorite vegetables, canned beans, Italian salad dressing, meat and cheese. I've already made it using cheese tortellini in place of some of the pasta. HINT: keep extra Italian dressing on hand as the pasta will soak up most of the dressing when it sets overnight.
Cook pasta al dente according to package directions. Drain and set aside.
Meanwhile, in a LARGE bowl, combine the olives, beans, green pepper, red pepper, orange pepper, onion, tomatoes, zucchini, pepperoni, Parmesan cheese, Italian seasoning and salt. Mix well. Add the cooked pasta and pour the dressing over all. Toss gently to coat all.
Cover and refrigerate for at least 2 hours, or until chilled.
