Spread butter over 1 side of each slice bread. Turn 2 slices over; top with 2 slices cheese, the roast beef, red peppers and remaining 2 slices cheese. Close sandwiches with remaining bread, buttered sides up.
Cook sandwiches in a preheated panini maker or greased waffle iron until golden brown and cheese is melted, 3 to 4 minutes. (Or, sandwiches may be cooked in a large nonstick skillet over medium heat 3 to 4 minutes per side.)
