In a medium mixing bowl, combine all of your ingredients for the salsa, then set aside.
Grate your zucchini and squeeze out much of the moisture (discard), then place zucchini into a large bowl.
Add in ground meat, garlic, all fresh herbs, crumbled feta, sea salt and pepper, then stir well to combine(I like to just get my hands in there to combine well).
Take about 2 large spoonfuls of your mixture and form into a burger patty, then with your thumb gently press into the middle (this helps the center cook evenly). Repeat with remaining meat.
Heat a large skillet over medium heat and drizzle with oil.
Add in the patties, and cook for about 3-4 minutes on each side, or until done to your liking. (If using ground turkey, your burger must be cooked thoroughly).
To serve, add lettuce leaves on a plate, then add your burger on top.
Add a few spoonfuls of chunky salsa and enjoy!
