Mix equal portions of ketchup, mayo, and relish (either dill or sweet). This sauce is SO easy and really makes the burgers amazing!
BAKE or GRILL the Cheeseburger Sliders
Cut 24 cheddar cheese 1" cubes from a large block of cheese.
In a large bowl, mix hamburger meat, grill rub, and Worcestershire sauce until well combined. Use a 2” ice cream scoop to get cheeseburgers even sized, place a 1/2" cube of cheddar cheese inside, and form into a ball. Place on the parchment-lined sheet pan if baking in the oven, or place on a tray to take to the grill.
Preheat oven to 400 degrees or Preheat the gas grill on medium high heat.
BAKE 400 degrees 20 minutes until well done or GRILL 8-12 minutes until well done.
Assemble burgers: slice buns, add burger sauce, stack lettuce, tomato, cheeseburger, 1/4 of a Colby cheese slice, and serve on a patriotic tray (or in cupcake wrappers) and stick a flag toothpick on top.
Cute serving idea: Try serving the cheeseburger sliders on patriotic cupcake wrappers on a tray, easier to eat and hold at a party!
