Make a day ahead for full flavor. Combine:

12 oz. pasta, cooked & rinsed (I prefer sea shells or macaroni)
12 oz. (approx.) diced sharp Cheddar cheese
10-12 diced sweet pickles
15 sliced green onions including some of the "green" for color
5-7 cans shrimp, the more the better (I use no less than 7)
3 c. Miracle Whip salad dressing (approx.)
5 sliced or diced hard boiled eggs.
