I want to add to the choices in "Easy Peas-y." I have been making and taking this side dish to gatherings for years. Pour a large bagful of frozen peas into a bowl, toss in pearl onions, some Old Bay seasoning, celery salt and a bit of curry powder. Let it sit out to thaw, then add shredded cheddar cheese and a cup of mayonnaise and refrigerate. Stir well, and voilà!
