Finely dice mushrooms and onions and add to a large bowl along with the minced garlic, oregano, black pepper, and salt. Stir to combine. Mix in the ground turkey then fold in the breadcrumbs and egg, mixing gently until incorporated. Form into 6 patties, roughly 4 ½ ounces each.

To cook on the stove top:

Set a large nonstick skillet over medium heat and spray with cooking spray. Place burger patties on skillet and cook 5 to 7 minutes per side, or until internal temperature reaches 165°F.

To cook in the oven:

Preheat oven to 375°F. Place burger patties on a baking sheet lined with parchment paper and bake for 20 to 25 minutes, flipping halfway through cooking. Remove when internal temperature reaches 165°F.

Serve burgers on whole wheat buns topped with leaf lettuce, tomato, red onion, and sauce of choice, we recommend Tzatziki.
