Macaroni Salad

Macaroni Salad 

1 lb. Tri-Color Pasta, Rotini, or Ziti cooked, strained, and cooled (I usually never remember to make this until last minute, so running under freezing cold water works if you do it for about 5 minutes)

4-5 Heaping Tbsp. Mayonnaise

1 small onion, diced
1 stalk celery, diced
1-2 Tbsp. Garlic Salt
1-2 Tbsp. Onion Powder
Salt and Pepper to taste

Take cold pasta, mix in mayo, add the rest of ingredients
