Start by mixing the onion mushroom soup mix in with the hamburger (I think this would be great with ground turkey).
Next you want to put your meat on some wax paper
Put another piece over and roll flat with a rolling pin
Cut them with a pizza cutter they were not round more square, cook in pan I could not get a picture because this goes pretty quickly. I used Hawaiian sweet rolls top with topping of your choice. Very Good! Thanks Meg for the inspiration!
