In a large bowl, combine chicken with avocado, bread crumbs, garlic, parsley and red pepper flakes. Stir well to combine and season with salt and pepper. Form the mixture into 4 patties.
In a large skillet over medium-high heat, heat vegetable oil. Place patties in the skillet and cook until golden brown on one side, 4 to 5 minutes.
Flip the patties, and cook another 3 to 5 minutes until cooked through, or until a thermometer inserted into the middle of the burger reads 165°.
Serve on a bun with lettuce, tomato and onion.
