Spray pieces of foil with cooking spray. Place onto each piece of foil:
A thin slice of onion
A thin slice or two of lemon
A tablespoon of pesto
Sliced grape tomatoes
Sliced zucchini
Salt and pepper to taste
Optional: A few raw shrimp
Fold foil over the ingredients to make packets; place packets on a cookie sheet. Bake at 350 degrees F. for about 25 minutes until salmon flakes easily with a fork.
