In a large bowl, mix ground turkey or chicken, spinach, feta, garlic, oregano, cumin, salt, and pepper until just combined without overworking the meat
Form the mixture into 4-6 burger-style patties depending on size preference
Heat olive oil in a pan over medium heat and cook patties for 5-6 minutes per side until golden brown and fully cooked through (internal temperature 75°C/165°F)
In a small bowl, mix Greek yogurt, olive oil, lemon juice, garlic, dill, salt, and pepper until smooth and adjust seasoning to taste
Add lettuce or greens as the base of the bowl
Top with cherry tomatoes, cucumber, red onion, olives, and optional quinoa or rice
Slice or place whole patties on top of the bowl
Drizzle generously with the creamy tzatziki-style sauce and serve fresh and slightly warm
