In small bowl combine mayo, ketchup, relish, and white vinegar. Set aside until ready to use.
Burger
Heat skillet or griddle over medium heat and coat with oil. Salt and pepper both sides of the patty and cook 3 minutes. Add mustard and flip burger, cooking an additional three minutes or longer, depending on your preference. Add cheese and allow to melt. Remove from heat and place on a toasted hamburger bun. Top with sauce and toppings of your choice.
Notes
Make this burger "Animal Style" by adding on some caramelized onions in place of the red onion.
This sauce goes great with french fries, so make sure to fire up a batch of fries to make this meal complete.
Perfect Pairing
Burgers always go great with milkshakes! These three milkshakes are the perfect way to wash a burger down.
