First make your classic burger in a sauce pan or grilled seasoned with your favorite seasoning.
Next take your green plantains, pill them and slice them in one inch pieces. Fry them in vegetable oil for roughly 2 minutes. Once brought out you will then mash them into a disk (you may use a cup to flatten) then put them back to fry for 2 or 3 minutes. Bring the plantains out and mash them into a stuffing type texture with fresh garlic clove, chicken stock and adobo to taste.
Tack a small ball of mofongo and roll in a ball and fatten into a bun shape about the same side as your burger. Put the burger onto and dress with your favorite burger toppings. Then take another ball of mofongo and repeat shaping to fit burger.
