Pasta Salad

This is the pasta salad from my childhood.  My sister Julie used to make it for every single family occasion.  It is really delicious and really easy.

Pasta Salad

1 lb shell noodles, cooked and cooled (Or macaroni noodles, whichever you prefer)
1 can olives, drained and sliced
2 chopped tomatoes, seeded
Bacon cooked and crumbled, if desired.
Green onion, chopped, if desired

Mix these together in a big bowl.

Dressing:
Mix together
1 cup mayo
1 cup sour cream
1 pkg powdered ranch dressing mix.

Stir 3/4 of the dressing onto the salad.  Let it sit for a little while in the fridge.  Add the rest of the dressing just before serving.
