How many people are you feeding? Are you going to make all five pounds?
A real good option is to take your favorite crab cake recipe and substitute shrimp.
Or pasta. For example, tonight I'm cooking the girlfriend steamed mussels, clams and shrimp tossed in olive oil, garlic, cherry tomatoes, Italian parsley, onion and crushed red pepper.
But my very favorite way to have shrimp is to lightly coat them in salt, pepper and olive oil and put them on a cookie sheet in one layer and bake at 400F for 9 minutes.
