Preheat oven to 400F.
In a large bowl, combine the ground meat, minced garlic, breadcrumbs, chopped parsley, lemon zest and seasonings. Mix well, then shape into 2 tablespoon sized meatballs.
Place in an oven-safe skillet over medium heat with olive oil to sear on both sides 1-2 minutes until golden brown.
Transfer to the oven to finish cooking 8-10minutes.
In a food processor, combine the yogurt, lemon juice, cilantro, and avocado. Blend until smooth, adjusting to taste with salt and black pepper.
Assemble your pita pocket with the baby arugula, diced cucumbers, and cherry tomatoes, tzatzhiki or hummus, the meatballs, and pickled onions.
