Chop all of your vegetables into cube size pieces and use a brush to coat them with a mixture of olive oil and garlic powder. Take a few cubes of each vegetable and put them on a metal skewer, leaving room for the cheese which will be added later. Place the skewers on a hot grill and grill for 4-5 minutes on each side or until you see some light grill marks on the vegetables. Take them off of the heat and put them on a cooling rack. Cut the grilling cheese into ¾” strips and add the strips to the vegetable skewers. Grill the skewer with the cheese for an additional 60 seconds on each side.
