8 slices Italian bread, 1/2 inch thick
2 tablespoons butter or margarine, softened
½ pound thinly sliced cooked deli roast beef
¼ cup basil pesto
4 slices (1 ounce each) mozzarella cheese
Pasta sauce, warmed, if desired

• Spread 1 side of each bread slice with butter. Place 4 bread slices, butter sides down, in 12-inch skillet or on grill pan. Top with beef, pesto and cheese. Top with remaining bread slices, butter sides up.
• Cook over medium heat 4 to 5 minutes, turning once, until bread is crisp and cheese is melted. Serve with pasta sauce.
