Sizzlin' Good Sandwich!
The key ingredient is not available everywhere, so when I am in a State that has them, I buy a bunch of them, freeze them, and take them home with me! My daughter, who no longer lives in MI, does the same.
Ask the company where they can be purchased. Stehouwer Frozen Sizzle Steaks. stehouwerfrozenfoods.com/contact-us
It isn't nearly as good with other brands of frozen sizzle/sandwich steaks. :(
Dark Rye bread is important, too.
Add 1 frozen Stehouwer Sizzle Steak
Slice Onion, Tomato and Cheese
Add cheese slice after turn steak to cook on other side.
Place onion slice on sizzle steak; then tomato slice on that.
Place other side of bread (buttered side on tomato).
Cut and serve.
