Cajun Shrimp in Foil

Preheat grill or oven to 425°F. Boil the potato chunks and corn for 10 minutes and remove to a plate to cool.
Meanwhile, cut four 12×12 inch pieces of foil. Place them on a work surface shiny side facing up.
Distribute the shrimp, sausage, corn and potatoes evenly between each piece of foil, arranging them in a pile in the middle. Then sprinkle Cajun seasoning on top and drizzle olive oil across the ingredients.
Life up two opposite edges of foil and bring them together, folding down a half inch so they hold. Then roll up the other two edges to seal tightly, taking care not to puncture the foil.
Place the packets seam-side up on the grill or oven rack and close the lid/door. Cook until the shrimp are pink and potatoes tender, about 15 minutes.
Remove each packet to a serving plate. Open the seams and let the steam escape. Then garnish with optional lemon and parsley before serving.
