Cook the pasta per package directions , making sure not to overcook. Place the peas in the colander and drain the pasta right over the top of the peas, this will cook the peas to a crisp tender doneness. Cool and lightly stir in the rest of the ingredients.
Chill at least two hours or overnight and serve. You may need to add more salad dressing or mayo as the pasta tends to absorb it the longer you store it.
