Myrna's Pasta Salad

From my sister's Mother-in-Law, Myrna

8oz rainbow rotini pasta (or I just use a whole 12oz box)
1 small pkg sliced pepperoni
1 cup chopped (fine) cauliflower
1 cup chopped broccoli florets
2-3 carrots, sliced
1/2 cup chopped celery
1/2-1 cup chopped green onions
8oz Monterey jack cheese, diced
Ripe olives, sliced

Mix together & then stir in 8oz Italian dressing (or more, if desired).

I usually omit the things I don't ike - celery & olives; and then I add sliced cherry tomatoes!
