Preheat your grill to medium-high heat or the oven to 400°F.

In a mixing bowl, season 1½ lbs of ground beef with salt, pepper, and garlic powder to taste. Mix thoroughly.

Shape the seasoned beef into four even patties, each about ¾ inch thick.

Lay out four large sheets of heavy-duty aluminum foil, each large enough to hold a portion.

Place approximately ½ cup of thinly sliced baby potatoes in the center of each sheet, layer onions and bell peppers, and add a burger patty.

Drizzle approximately 1 tablespoon of olive oil over each assembled pack of veggies and the burger. Sprinkle additional salt and pepper.

Fold the foil over the ingredients, sealing each packet tightly.

Place the sealed foil packets on the preheated grill or in the oven and cook for 25-30 minutes.

Once cooked, carefully unwrap the foil packets. Sprinkle shredded cheddar cheese and add your favorite toppings.
