PREHEAT oven to 425°F. Spread one side of each bread slice with butter. Place 4 of the bread slices on greased baking sheet, butter-sides down. (Butter on the outside browns the outer crust.) SPREAD bread slices on baking sheet with mustard. Top with Meat, veggies and Cheese; cover with remaining 4 bread slices, butter-sides up. BAKE 6 min. or until golden brown; turn over. Bake an additional 6 to 7 min. or until sandwiches are golden brown on both sides.
