Mix the vegetables into the meat. Add the carrot, cilantro, onion, garlic, cumin, salt, and pepper to the ground turkey. Mix thoroughly with your hands until everything is evenly distributed.
Shape the patties. Divide the mixture into equal portions and form them by hand. Don't make them too thick or the centers won't cook through evenly.
Cook with no oil. Place the patties in a hot skillet with no oil or butter at all. Let them cook on one side until nicely browned, then flip once. Ground turkey needs to be fully cooked through with no pink in the center.
Serve. Remove from the skillet and build your burger on the bun with lettuce, tomato, and onion.
