These burgers are a great way to use up any leftover biscuits you have around. Pretty much any flavor will do!
If you are not a fan of onion rings or do not have any around, you can swap in French fries!
This burger can also be fried in a skillet. Heat oil in skillet or griddle over high heat until oil begins to shimmer. Cook burgers in oil until golden brown and slightly charred on the first side, about 3 minutes. Turn burgers over. Cook until golden brown and slightly charred on the second side, 4 minutes for medium rare or until cooked to desired degree of doneness.
