BURGERS: For best results, thaw beef burgers in the refrigerator for one day in advance. Season beef burgers with salt and pepper. Place burgers on hot, oiled grill. Grill burgers for 5 minutes each side, until cooked through. About 2 minutes before beef burgers are done, brush on extra virgin olive oil to both sides to keep in moisture and reduce drying.
SALSA: Remove seeds from tomatoes and discard. Chop remaining tomatoes into pieces (about 1/4" each) In a medium mixing bowl, combine chopped tomatoes, chopped red onions, chopped fresh dill, lemon juice, 2oz extra virgin olive oil, and salt and pepper to taste. Toss and set aside.
TZATZIKI: A store-bought tzatziki sauce of your preference will work for this recipe. Of course, fresh-made tzatziki will taste better. If not pressed for time, then combine the following
1 tbsp. vinegar
2 garlic cloves garlic, minced finely
1/2 tsp kosher salt
1/4 tsp ground white pepper
1 cup thick greek yogurt
1 cup sour cream
2 cucumbers, peel, remove seeds, and dice
1 sprig chopped fresh dill, stem removed
Spread tzatziki sauce onto bottom portions of flatbreads.
Add beef burgers.
Spoon on red onion tomato dill salsa.
