2 cans (one 12 ounces, one 5 ounces) albacore white tuna in water, drained and flaked
1/4 cup reduced-fat mayonnaise
1-1/4 teaspoons dill weed, divided
8 slices cheddar cheese
8 slices tomato
Preheat broiler. In a microwave, melt butter with garlic. Place rolls on a baking sheet, cut side up; brush with butter mixture. Broil 2-3 in. from heat until lightly browned, 2-3 minutes.
In a small bowl, mix tuna, mayonnaise and 1 teaspoon dill. Layer roll bottoms with tuna mixture and cheese. Broil until cheese is melted, 1-2 minutes longer. Top with tomato; sprinkle with remaining dill. Replace tops; serve immediately.
