1 lb lump crabmeat
1/3 cup fat-free mayonnaise
1/4 cup water-packed roasted red peppers, minced
2 tsp Dijon mustard
1/4 tsp table salt
1/4 tsp freshly-ground black pepper
4 slices pumpernickel bread
3 oz low-fat Swiss cheese


Preheat broiler.
Combine crabmeat, mayonnaise, peppers, mustard, salt and pepper in a medium bowl; gently toss to combine. Divide crab mixture among bread slices, transfer to a baking sheet and top each with one slice of cheese.
Broil until cheese is golden and bubbly, about 1 to 2 minutes.
