4 LB shrimp (unpeeled and headless)
1 large onion (cut into rings)
2 lemons (sliced)
1 large bottle zesty italian dressing
1 TSP black pepper (or to taste)
Temperature: 375-400
Place the shrimp in deep pan and cover with the other ingredients. Bake for 1½ hours until onions are tender. If sauce is too thin, reduce by simmering longer.
