In a large bowl mix together turkey, cilantro, garlic, Worcestershire, paprika, cumin, granulated garlic, onion powder, salt, and pepper, until combined. Form into 4 patties.
Heat a large non-stick skillet to medium-high heat; coat with the oil. Add burgers and cook for about 4 minutes on each side, or until cooked to 170 degrees and no longer pink in the center. Place cheese slices on top of burgers and cover or tent with aluminum foil to melt cheese.
Place burgers on buns and top with avocado slices (1/4 of the avocado per person), jalapenos (if using), and tomatoes.
