Combine all ingredients and divide into 8 equal portions. Roll into balls and then flatten into little burgers. Grill on a barbecue or grill pan over medium-high heat for 2 -3 minutes per side. Do not over cook.
Serve the sliders on the Greek Slider Buns with the Quick Tzatziki Sauce and sliced vegetables on the side.
Quick Tzatziki Sauce
Combine all ingredients. Taste and adjust seasoning with more salt and pepper if needed. Can be served right away but is best if refrigerated for at least half an hour. Can be made a day ahead. Stir before serving.
Greek Slider Buns
Preheat oven to 375 degrees. Brush 8 cups in a standard muffin pan with olive oil or spray with gluten-free non-stick cooking spray.
Combine all ingredients in the bowl of an electric mixer and mix on low to combine, scraping down the sides of the bowl once. Increase speed to medium-high and mix for 3 minutes. Divide the batter evenly among the prepared muffin cups (about 2 tablespoons per cup) and bake for 15 minutes or until the buns are golden brown
