Cook ravioli according to package directions, adding the sugar snap peas during the last 2 minutes of cooking. Drain; transfer to a serving platter and keep warm.
Meanwhile, in a large skillet cook onion in hot margarine or butter over medium heat for 4 minutes. Stir in whipping cream, the 1/4 cup dill weed, parsley, lemon-pepper seasoning, and lemon peel. Bring to boiling; reduce heat. Boil gently, uncovered, about 2 minutes or until slightly thickened. Spoon cream sauce over pasta and pea pods. Toss gently. Sprinkle Parmesan cheese over all. Sprinkle with additional snipped dill weed, if desired. Makes 4 to 6 main-dish servings.
