(aka ‘foil dinners’ +!) Rachel (who found this recipe) is being annoying right now and says “mmm I have no idea” when I ask her for details about this recipe. Actually, it is really good - the cheddar and Worcestershire are good additions to the traditional campfire recipe.
Heat coals or gas grill for direct heat. Spray half of one side of four 18x12” sheets of heavy duty aluminum foil with cooking spray.
Mix beef, cheese, Worcestershire sauce, 2 Tbl chopped onions, and 1 teaspoon seasoned salt. Shape mixture into 4 patties, about 1 inch thick. Place potatoes on sprayed sides of foil sheets. Top with beef patty, carrots, tomatoes and sliced onions; sprinkle with 1/2 tsp seasoned salt. Fold foil over patties and vegetables so edges meet. Seal edges, making tight 1/2” fold; fold again. Allow space on sides for circulation and expansion.
Cover and grill packets 4-6” from medium heat 20-30 minutes or until potatoes are tender, turning packets half way through. Remove from heat; cut large X across top of packet; fold back foil. CAUTION: steam will escape - contents will be very hot!
