Once again the finalists are... "Cheddar" by Florencia, "Salsa Criolla" by Tato (Salsa Criolla is a salsa composed of sliced onions and cilantro, pickled beets, boiled potatoes, avocado, chili peppers and tomatoes), and "Hamburger" by Vanesa.
Let me know if you try these!! Please!
UPDATE: These are also being sold now at Burger King locations in Argentina! How fun! You can snag a bag with a combo instead of the usual French Fries. Great Idea!!
