3 English muffins, split and toasted
3 tbsp. butter
1 lg. tomato, cut in 6 slices
1 can (6 1/2 oz) tuna, drained and flaked
2 tbsp. mayonnaise
3 slices cheddar or Swiss cheese

Spread muffins with butter. Arrange in circle on large paper towel-lined microproof plate. Place tomato slice on each muffin. Mix tuna and mayonnaise until blended. Divide and spoon tuna over tomato slices. Cut cheese diagonally in half to form triangles. Place 1 triangle of cheese on each muffin. Use "defrost" cycle and cook 7 to 8 minutes or until cheese melts and muffin topping is warm. Let stand 2 minutes before serving.

A single split muffin can be prepared and cooked on "defrost" cycle for 1 to 1 1/2 minutes. Toasted bread can be substituted for English muffins.
