Fold 2 slices of Velveeta per hamburger patty. Velveeta has a super low melting point.
Place in the center of your patties.
Seal your patties by pinching all edges together well.
Liberally sprinkle patties on tops and bottoms with salt, pepper, garlic and onion powder.
Throw on a hot clean grill.
Grill for 3 minutes on each side.
You'll know they're done when your cheese oozes out of your patties. Sides and tops.
Lightly butter, season and grill your buns. Optional.
Chop your chilled vegetables and gather 2 more Velveeta slices.
Add Mustard.
Construct your double burgers. Serve piping hot!
Enjoy!
