Cut some onions into strips and slice or chop some cloves of garlic.
Put a skillet on at medium high and eyeball just enough olive oil to cover the bottom.
Put the beef, onions and garlic into the skillet. Sprinkle some salt and pepper.
Stir or toss it all a few times as it cooks. When it all is almost cooked to how you want it to be, when served, spread it all out and lay the slices of cheese on top.
When the cheese has melted put your philly cheesesteak onto some Italian bread or rolls. Or, just serve it with the bread on the side and let your tribe put it together any way that they want.
