Mozzarella-Stuffed Turkey Burgers

FOR THE MARINARA:
Heat 2 teaspoons oil in a medium saucepan over medium heat. Add onion and garlic, cover and cook, stirring frequently, until translucent, 5 to 7 minutes. Stir in fresh tomatoes and any juices, sun-dried tomatoes, 1/2 teaspoon salt and 1/2 teaspoon pepper. Bring to a simmer and cook, stirring occasionally, until the tomatoes have broken down, 8 to 10 minutes. Stir in basil and remove from the heat. Transfer to a food processor and pulse to form a coarse-textured sauce. Return to the pan and set aside.

FOR THE BURGERS:
Place turkey, scallions, garlic, Worcestershire sauce, lemon zest, oregano, 1/2 teaspoon pepper and 1/4 teaspoon salt in a large bowl. Gently combine, without overmixing, until evenly incorporated. Form into 8 thin patties about 4-inches wide and 3/8 inch thick.

Combine 1/4 cup cheese and basil and place an equal amount in the center of 4 patties. Cover with the remaining patties and crimp the edges closed.

Heat 2 teaspoons oil in a large nonstick skillet over medium heat (see Grilling Variation). Add burgers and cook, turning once, until an instant-read thermometer inserted in the center registers 165 degrees F, 8 to 10 minutes total.

Warm the marinara on the stove. To assemble the burgers, spread 3 tablespoons of marinara on each toasted foccacia, top with a burger, about 3 more tablespoons of marinara and 1 tablespoon of the remaining cheese. Grilling Variation: To grill the turkey burgers, preheat a grill to medium-high. Oil the grill rack (see Tip). Grill the patties, turning once, until an instant-read thermometer inserted in the center registers 165°F, 8 to 10 minutes total.
