buns, sliced tomatoes, lettuce, and pickles, for serving
Directions
In medium skillet, heat 1 teaspoon of the olive oil over medium heat until shimmering. Add the mushrooms and garlic, and sauté until the mushrooms are soft, 3 to 4 minutes. Remove from the heat and set aside to cool.
In a large bowl, mix together the turkey, wheat germ, mustard, cheese, black pepper, and cooked mushrooms. Form into 4 patties or 8 sliders. Grill on the barbecue or in a preheated grill pan until cooked through, about 5 minutes per side. Brush with the remaining 1 tablespoon olive oil and serve immediately with all the fixings: buns, sliced tomatoes, lettuce and pickles.
