Mix all spices together in a small jar or other container and shake. This will keep for weeks.
I like to use peeled and deveined shrimp, because it’s less messy for guests.
A large roll of aluminum foil
Cut a piece of foil about a foot and a half long.
Place 3 corns, a handful of green beans, and four shrimp in the center of the foil, arranged in a sort of rectangular pile. Lightly squirt with a lemon wedge and then add the lemon wedge to the pile. Sprinkle with about a half teaspoon of Cajun seasoning, or more if desired. Fold edges over so liquid produced while cooking will not leak out, and top is covered.
Heat grill to high, and place packets directly onto grill.
Do not flip.
Cook for about fifteen minutes, until corn and shrimp are cooked.
Serve in packets, with plenty of napkins!
