1 and 1/2 pounds ground turkey
1/2 cup finely grated Gruyere cheese
4 scallions, thinly sliced
1/4 cup dried breadcrumbs
1/4 cup Dijon mustard
1 garlic clove, minced
4 English muffins, split and toasted
mayonnaise, sliced tomatoes, and lettuce, for serving
Heat the grill to high. In a medium bowl, use a fork to gently combine the turkey with the Gruyere, scallions, breadcrumbs, Dijon mustard, and garlic; season generously with salt and pepper. Dividing the mixture evenly, gently form into four 1-inch-thick patties.
Lightly oil the grill. Place the patties on the hottest part of the grill; sear until browned, 1 to 2 minutes per side. Move the patties to a cooler part of the grill; continue grilling until cooked through, 5 to 10 minutes per side.
Build burgers as desired.
