Forgive me blog readers, for I have sinned.
I have sinned by making and eating this demon-infested sandwich, which is (1) slathered with a tremendous dollop of mayonnaise, (2) stacked with pieces of divine (yet artery-hardening) steak, and (3) overwhelmingly loaded with huge 1/4 inch slices of real cheddar cheese. Basically, the "demons" are full-fat mayonnaise, oily cheddar cheese, and red meat.
"If it is so sinful, then why make this sandwich?" Because!
Because it reminds me of my childhood. When I was a little girl, my Dad used to make us steak and mayonnaise sandwiches with the leftover steak in our fridge. To me, this sinner's steak sandwich is the ultimate comfort food.
I have some precise instructions on how to make this sandwich. You first need to toast the bread in a toaster, oven, or in a non-stick frying pan. And just use plain white or wheat bread here folks. Nothing fancy is needed. If you go the "oven" or "frying pan" route, do not use butter or oil. Just monitor the dry pieces of bread as they toast and turn them before they scorch.
Next, layer the toasted bread with thick slices of cheddar cheese and put the bread in the microwave for about 30 seconds. (I like to layer both bread slices with the cheese.) When the cheese is "melty" (meaning, it does not need to be fully melted), you are ready to add the mayo and the steak.
The key to this sandwich using a large ladle-sized tablespoon to heap an unhealthy amount of mayonnaise (small ice cream scoop-sized) all over the cheesy bread. Do not, I repeat, "do not" delicately smear a slight amount of mayonnaise on the surface of the bread. And do not feel bad when you are making this sandwich. If you imagine an electric guitar playing hard rock music in the background, you will feel much better about ingesting all that mayo and cheddar cheese.
Next, nestle slices of leftover steak into the little mountains and canyons of mayo on one open slice of the bread, and then put the entire sandwich together.
So your sandwich layering should go like this from the top to the bottom: (1) toasted bread slice, (2) melted cheddar cheese, (3) mayonnaise, (4) steak, (5) melted cheddar cheese, again, and (6) toasted bread slice.
It is not rocket science, but it is extraordinarily sinful, and making and eating this 'wich will definitely hasten a visit to the underworld. If you are looking for a healthy version of the sinner's steak sandwich, try (1) using whole grain wheat bread, (2) adding a mere tsp of non-fat or low-fat mayonnaise, (3) reducing the cheese by 1/2, and (4) removing all fat from the steak, before inserting it into the sandwich.
