We had fresh green peas this past Sunday at my in-law's house, and they were worth every penny of the exhorbitant price they commanded at the farmer's market! This is the way my mother-in-law cooked them; this recipe is from an older edition of the Better Homes and Garden New Cookbook. 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.
2 pounds fresh peas, unshelled
3 to 6 lettuce leaves
1/3 cup sliced green onion
1 teaspoon sugar
1/2 teaspoon salt
dash dried thyme, crushed
3 tablespoons butter or margarine
Shell peas. Cover bottom of skillet with lettuce; top with peas and onion. Sprinkle on sugar and seasonings; add butter. Cover tightly and cook over low heat 10 to 15 minutes or till peas are done. Serves 4.
