Begin by loosely forming ⅓ lb squares of ground beef, set onto a tray and place in the fridge to firm for 30 minutes. In another bowl, mix together all the ingredients (making sure to use those Primal Kitchen sauces) for your Diner Sauce and set that in the fridge until you are ready.

Preheat your grill to medium high heat (around 350F) adding a cast iron skillet/plancha to the grill 2 minutes before cooking.

First, add your bacon to cook on the skillet. Cook until done to your liking, then pull off and let cool. Next, add the thinly sliced white onions. Saute the onions for 25-30 minutes until they become crispy, browned and soft. Pull the onions off once done and set to the side.

Next, pull your burger patties out of the fridge and add to the skillet. Cook for 2 minutes on the first side or until they begin to caramelize. Flip the patties over and gently “chop” the meat so that the ground beef patties loosen up and get a larger surface area. Cook for 2 minutes, then flip the patties back over. Mix together your three types of cheeses, top each patty with some onions, cover with a handful of cheese and let melt. Pull the patties off and let cook for 2 minutes. While the patties cool, add some Primal Kitchen Mayonnaise to each side of your toast, then cook your bread over the flames to a nice golden brown.

Start assembling your patty melt with a spoonful of the Diner Sauce on the bottom piece of, 1-2 patties, bacon slices and more sauce for the top piece of toast. Serve and enjoy!
