This is a standard offering at my in-laws' Sunday lunch table (which is always full of guests or family). I just found out that this recipe comes from an older edition of one of my favorite cookbooks: Better Homes and Garden New Cookbook. Why do they change a good thing? But I digress. We've tried to find the publication date and can't. It's not the 1953 edition now out in facsimile; she was given it when she got married in 1971. These beans are yummy!
2 9-oz. packages frozen cut green beans
1/2 cup finely chopped onion
2 tablespoons butter or margarine
1 teaspoon sugar
1 teaspoon seasoned salt
1 teaspoon vinegar
1 cup dairy sour cream
Cook beans according to package directions. Cook onion in butter till tender but not brown. Add remaining ingredients and dash pepper; heat through (do not boil). Drain beans; top with sauce.
Serves 6 to 8.
Make Ahead Note: my in-laws cook the onions for the sauce before church, so everything is easy to throw together after church.
