I have two brothers, both of whom like to cook. My oldest brother concocted this wonderful way to prepare peas several years ago, and it's delish:
1 bag frozen peas
1 whole onion, diced
1/2 package fresh mushrooms, cut up or sliced
1 tsp parsley
1 tsp garlic salt
3/4 c white cooking wine
2 heaping tsp butter or margarine
Cover and cook slowly until peas are done
