I used @athenosfeta to create this double smash feta burger because everything is better with feta! #FoodNeedsFeta #athenospartner Recipe: 1 Pound 80/20 ground beef Onion sliced Tomato sliced Cucumber Spinach Potato Buns Feta cheese crumbles Tzatziki sauce 1 Tbsp white wine vinegar 1 Tsp sugar 1/3 Cup olive oil 4 Garlic cloves minced 1/2 Cup plain whole milk Greek yogurt 1 Tsp dried dill 1 Tsp oregano 1/2 Tsp freshly ground black pepper 1/2 Tsp sea salt 2 Tbsp lemon juice (Optional: add diced cucumber to sauce) Add all sauce ingredients to a jar and shake until fully combined. Set aside. Form the beef into 6 even sized balls. Place in a pan over high heat and smash down with a spatula until thin. Season with salt and pepper. Cook on both sides until crispy. Add feta cheese to a patty and top with another patty. Assemble burger by placing down sauce, spinach, tomato, burgers, more feta cheese, red onion, cucumber strips,and more sauce. Enjoy!
