Preheat oven to 400 degrees. Line a large rimmed baking pan with parchment paper.
Drain chickpeas, reserving aquafaba from can (this is the liquid that the chickpeas are in and you will need it for another part of this recipe!). Rinse chickpeas well.
Add chickpeas, sweet potato and garlic to food processor and pulse lightly. You want a mixture that is chunky but not puréed. Gently fold in your flax egg.
Form this mixture into 5 or 6 vegan burger patties.
In a small shallow pan, pour your aquafaba.
In another shallow pan, combine dairy free ranch mix, nutritional yeast and panko.
Form an assemble line with your patties and two shallow pans.
Dip your burgers in aquafaba and then coat with your panko mix. (see not on leftover panko mix)
Place on parchment lined baking pan.
Bake at 400 degrees for 15 minutes. Flip burgers and bake additional 15 minutes.
