Chop all of the ingredients to 1.5″ square pieces except for the bacon and mushrooms. Leave the mushrooms whole. Thread one end of the bacon onto the skewer. Then add a vegetable or fruit piece. Wrap the bacon around the vegetable or fruit, pressing the skewer through the bacon again. Repeat until the skewer is filled. Lay the skewers on the Kabob Set rack and place on a hot charcoal grill. Close the lid of the grill and cook until the bacon is crispy and the vegetables are tender, about 15 minutes. Use the disc on the skewer to slide the vegetables, fruit, and bacon from the skewer.
