Healthy Philly Cheesesteak

Sauté the onion in a medium skillet with the beef juice for 5 minutes. Next add the green pepper and mushrooms and sauté an additional 5 minutes.

Heat a griddle over the stove. Divide the beef into 4 equal parts. Grill 2 parts of the beef on the griddle (more if the griddle is large enough) for 2-3 minutes, flipping a few times. Next add 1/4 cup of cheese to each part, cover and cook until melted, about 1 minute. Repeat with the remaining two parts of beef and cheese.

While beef is cooking, heat slices of bread, slice side down, on the griddle for 1 minute apiece. Serve the beef on the buns and top with onions, peppers and mushrooms.
