Bolivian asaditos are patties or burgers made with beef and shredded cassava.
In a big mixing bowl, add all the ingredients (except vegetable oil) and mix well.
Make ahead: Prepare and shape patties. Place parchment paper on 2 trays. Place patties on paper and place tray in the freezer for 3 hours. Remove and place frozen patties in a ziplock bag. Place in the freezer again.
Before using, defrost patties in the fridge overnight and cook.
