Instructions
Form the Burgers:
In a large bowl, combine the lamb, beef, shallots, garlic, salt, oregano, cumin, paprika, and pepper and mix until just combined (be careful not to overwork the meat). Form into 4 (1/2-inch thick) patties. Set aside.
Make the Easy Tzatziki:
In a small bowl, combine the yogurt, cucumber, olive oil, garlic, dill, lemon juice, vinegar, and salt. Stir to combine, then cover and chill until ready to serve.
Prep the Grill:
Preheat the grill over medium-high heat (about 400°F). Dip a wadded paper towel in the avocado oil and, using tongs, wipe the oil evenly over the grates. Be careful not to use too much oil to avoid starting a flare-up—a little goes a long way here.
Grill the Burgers:
Place the burgers on the grill and cook for 3 to 4 minutes. Flip and cook until the burgers are done to your liking, about 3 more minutes for medium. Remove from the grill and let rest for 5 minutes.
Serve in the pita pockets filled with lettuce, tomato, onion, and tzatziki.
