Add 2 of the 4 cheese slices of choice on 2 onion rounds and set aside on a plate. Cover to keep warm and help the cheese melt.
To the same preheated skillet, add the patties and cook until it start to get golden brown for about 3 minutes per side, then flip them and add the remaining cheese slices of 2 of your cooked patties. Continue to cook for 1 more minute, or just until the cheese starts to melt.

Notes
Do use large onions
You can use lean ground chicken or ground turkey.
Use any cheese of your choice, like American, cheddar, or provolone.
Work with care. It is a bit messy and hard to handle when making. It is expected to just work slowly when assembling the burger.
