Fork and Knife Steak Sandwiches
Serves 4

This hearty sandwich eats like a meal and can be made ahead and heated under the broiler just before serving.

1 tablespoon extra virgin olive oil
1 large onion, sliced
¼ cup mayonnaise
1 tablespoon whole grain mustard
4 thick slices sourdough bread
1 pound New York strip steak, cooked, trimmed of fat, and sliced
Salt and pepper
4 thick slices Swiss or Cheddar cheese

Heat olive oil in a large skillet over medium heat; add onions and cook until softened and golden brown, stirring occasionally. Remove from heat and set aside.

Combine mayonnaise and mustard, and spread onto bread slices. Lay bread onto a broiler pan lined with foil, and then top each with roast beef, salt and pepper to taste, onions, and a slice of cheese. Place under the broiler just until cheese is melted and sandwich is heated through. Serve immediately.
