Tuna Salad

This is another great summer salad! However, it makes a lot (it's intended for a big gathering) so I always half the recipe!

12 oz. elbow or small shell pasta, cooked, drained and cooled.
4 cans tuna, drained
2 c. celery chopped
2 cans olives, sliced or chopped
1/2 red pepper
1/2 green pepper
1 c. cubed cheddar cheese
1-2 c. frozen peas, thawed (depending on how much you want)

Dressing:
1 1/2 c. miracle whip
3/4 c. sour cream
1/2 c. milk
1 t. salt
1/2 t. pepper
1 t. basil
1/2 t. dill weed
1/2 t. paprika
1/2 t. onion powder
