This isn't "creamed peas", but it is a very good, quick and easy recipe to get close to the same effect.

Pea Casserole

1 can sweet peas (drained)
1 can condensed cream of mushroom soup (NOT diluted)
1 small onion chopped
Shredded Cheddar Cheese (add as little or as much as desired)
Crushed Crackers (use whatever kind you want--be creative)

Spray non-stick cooking spray in small oven ware dish. In a medium bowl,add peas, soup, onion, and cheese. Toss gently to coat. Pour mixture into the baking dish. Sprinkle the top with crushed crackers and extra cheese (if you like) and pop into the oven (set at about 350) for about 15-20 minutes (Basically until the cheese melts since everything else is cooked).
