In a large bowl, combine the ground turkey, grated apple, dried sage, dried thyme, garlic powder, onion powder, sea salt, and black pepper.
Mix gently with your hands until the ingredients are just incorporated, being careful not to overwork the meat.
Form the mixture into four equal-sized patties, approximately half an inch thick.
Heat the avocado oil in a large non-stick skillet over medium heat.
Place the patties in the skillet and cook for 5-6 minutes per side until golden brown and cooked through to an internal temperature of 165°F.
Remove the patties from the skillet and set aside; in the same pan, add the baby spinach and sauté for 1-2 minutes until just wilted.
Plate the turkey patties with the wilted spinach and top with the sliced avocado.
