The GF wanted patty melts.
So made up 6 oz patties from some ground chuck picked up a loaf of Beefsteak seeded rye bread, there was no fresh rye bread at the bakery, neither of us are fond of swiss cheese so I have provolone and she wanted white American, I sliced up about 6 yellow onions and caramelized.
I cooked the onions down to much for my liking, very sweet flavor, and one that you would remember for hours after you ate them.
They were good, don't think I ever made them before, and probably only ever ate one that I can remember. Things to change for next time, don't cook the onions down as much and use less butter and oil to do them, and for her use Texas toast, she didn't care for the rye bread.
Also ran 2 potatoes through the mandolin to make french fries (kind of) and just did them on the griddle also.
