In a large mixing bowl, combine the Ground Chuck, Ground Sirloin, and Ground Short Rib.
Slowly mix in the egg until you get a slightly sticky consistency.
Mix in the kosher salt and ground pepper.
Form balls with the mixture approximately 2" to 3" in diameter. Place on parchment or waxed paper and flatten to desired thickness. Make a small indentation in the middle of the patty to help lock in juices.
Season the burgers with the Coffee Spice Rub.
Cook on a grill at medium heat, flipping at the 5-minute mark. Cook burgers to medium doneness of 160° F internal temperature.
Spread the garlic mayo evenly on both sides of the bun. Place burger on bun heel. Add sliced tomatoes. Top with Herb Salad.
