While the coals are getting hot I get the hamburgers , hot dogs , cheese and buns . They sizzle and pop while they cook . I roll the hot dogs back and forth with a tong and when the hamburgers are ready I flip them over with a spatula . I put cheese on the top of them so it can melt . As soon as the hot dogs and cheeseburgers are done , I put the toasted buns on the plates and put the hot dogs and cheeseburgers on the plates .

Its a great summer night dinner . Question: When do they put the hamburgers on? Option1: when the coals are hot Option2: while they clean the grill
