Another simple side dish recipe my Mom used to serve when it was too hot to cook. Goes with heated up leftover meats and potatoes or thinly sliced cold beef, chicken or ham and potato salad.

1 can of sweet peas with liquid
1/2 small onion thinly sliced
2 ribs of celery chopped

Combine ingredients in a bowl. Stir well. Cover and refrigerate several hours or overnight. Serve cold.
