Step 1

Preheat grill to 350 degrees.

Step 2

In a bowl combine the hamburger, egg, seasoning salt and garlic powder. Form into four patties, set aside.

Step 3

In a large bowl combine the remaining ingredients except cheese slices. Mix until combined.

Step 4

Spray four 12'' x18'' pieces of foil with nonstick spray. Place 1/4 of the vegetables in the center of the foil. Top with 1 beef patty. Seal packets and place beef side up on the grill.

Step 5

Grill for 35-45 minutes or until potatoes and carrots are tender and the ground beef reaches 160 degrees F. I flipped mine over during the last 20 minutes of cooking.

Step 6

When the packets are done open the top, hamburger patty facing up, and add a piece of cheese. Close grill cover and grill 2-3 minutes or until cheese is melted.
