cup sliced onions
Directions
Slice your filet into thin strips. (Freezing it slightly beforehand will make it easier to cut.)
Cook onions over medium-high heat in a pan spritzed with nonstick spray for about 5 minutes, until onion slices are slightly browned. Remove onions from the pan and set aside.
Spritz a little more nonstick spray into the pan (remove pan from heat before re-spraying) and cook filet strips over medium-high heat for 1 to 2 minutes, flipping them halfway through cooking.
Place cheese on top of meat (still in the pan) and continue to cook until cheese is slightly melted.
Meanwhile, warm or toast your bun. Place meat and cheese in the bun and then top with onions. Enjoy.
Leaner cuts include filet mignon and sirloin
Fattier, marbled cuts include shell steak and rib eye. These often contain more calories than leaner steak cuts
Your best bet is often the filet mignon. Not only is it leaner but it's also often served in smaller portions than other cuts
