Tomorrow night I want to try a meatloaf that Bobby Flay did on one of his shows, it has chopped zucchini, peppers and garlic in it, and it's done not in a loaf pan but on a baking sheet, you make a "meatloaf mountain" and put a ketchup/balsamic glaze over it. He baked his in an oven at 425 for an hour to hour and a quarter, but on the egg would I be better to cook it 300?
