How to Make It
Heat the grill to medium-high. Divide the meat and gently form it into 4 balls. (Do not overwork the meat.)
Flatten the balls into 3/4-inch-thick patties. Flatten the top and sides of each patty to ensure that the thickness is the same throughout. Use your fingers to make a shallow well in the top of each patty. (This will prevent overplumping.) Season the patties with 1/2 teaspoon each salt and pepper.
Oil the grill grate using a pair of tongs and a paper towel dipped in canola oil. Cook the burgers (with the wells facing up) until they release easily from the grill, 4 to 5 minutes for medium. Flip and cook until an instant-read thermometer inserted in the center registers 155°F, or 4 to 5 minutes for medium. Serve on rolls with the desired toppings.
