Preheat grill to 350 degrees. Cut 4 (18x18) pieces of heavy-duty tin foil.
Lay a piece of fish on each piece tin foil. Layer lemon pieces on fish followed by a sprig of rosemary.
Continue to layer the next three ingredients (yellow squash through grape tomatoes). Sprinkle with sea salt and freshly ground black pepper and drizzle olive oil over all ingredients.
Fold 2 edges of tin foil together. Crimp all along the fold. Fold and crimp the other 2 sides until each is a closed and secure package.
Place each package in the middle rack of grill. Close lid and grill for 12-14 minutes, checking to see if fish is done and flakey. Remove and serve warm.
