Preheat a gas grill to 450 F.
Cut four 12 x 14 in pieces of aluminum foil.
If chicken breasts are too thick, tenderize with meat mallet, until they are 1 - 1 1/2 inches thick.
Season chicken breasts with salt, pepper, paprika, garlic and onion powder, oregano and parsley.
Place half of the potatoes over one piece of foil. Season with salt and pepper to taste.
Add half of the carrots, 2 pieces of corn, half of the onion and top with one chicken breast. Add 1 tbsp olive oil and at least 1 tbsp butter.
Carefully wrap the chicken and veggies in the first piece of foil. Wrap in another piece of foil, to prevent leakage.
Repeat with the remaining vegetables and the second piece of chicken.
Grill packets for 20-25 minutes at 450 F. It the meat appears undercooked, wrap again and cook for a few more minutes.
Serve and enjoy!
