More than a sandwich! It’s a meal.
Make cheese sauce: Melt butter, add flour, whisking, and cook about one minute until the flour begins to look drier but isn’t yet starting to brown. Add milk bit by bit, stirring until smooth each time, and cook, stirring till quite thick, about 5 minutes. Remove from heat, stir in cheese, Sherry, salt, and onion powder.
Assemble sandwiches: Preheat broiler. Arrange bread on a large cookie sheet. Top each with two ounces of turkey or ham, two slices tomato or asparagus, a sprinkle of pepper, bacon, then cheese sauce. Add grated cheese on topo if you wish. Sprinkle paprika over the top, if desired.
I often use three pieces of bacon for every two sandwiches – I don’t like it “hanging” over when it is broiled, so I when I think about it, I remove the extra and piece together on one of the sandwiches.
Broil till lightly browned and serve piping hot. Serve with crunchy slaw, pickles or a salad.
