Double Cheeseburger – Meat vs. Beyond: Homemade burger buns, a double cheeseburger, grilled red onion, and a special homemade sauce. Finger licking good!
Mix together the mayonnaise and mustard and set aside.
Grill the onions in a little oil until just tender. Transfer to a small plate and set aside.
Season the hamburger or Beyond Burger with salt and pepper. Make two 3-ounce patties for each hamburger sandwich and two 3-ounce patties for each Beyond Burger sandwich.
Add a tablespoon of butter to a frying pan and toast the rolls in the butter, cut side down until golden brown. Transfer to a plate.

Heat two separate cast iron frying pans until very hot. Add the meat burgers to one frying pan, and the Beyond Burger patties to the other. Fry the meat patties about 1 to 1 1/2 minutes on each side. Fry the Beyond Burger patties two minutes on each side. When you flip the burger over add the cheese to the burger
