GRILL kabobs until meat is cooked through, turning occasionally, means to cook "WELL DONE" on beef, pork and chicken. Sometimes when this is done, those veggies added with the meat will be over cooked and fall apart, it's better to do them on their own, till done, or warp in foil, add a ice cube to them, some butter and season, put them on grill for about 15 to 20 minutes, and, steam them. Plus ALWAYS make sure the grill grate (cooking-top) is clean before grilling.
