Combine all the ingredients except for the vegetable oil in a large bowl. Form the mixture into 30 small burger patties, around 2 heaping tablespoons each. 

Preheat a large cast iron pan and lightly grease with a thin layer of vegetable oil. Fry the patties, 5-6 at a time, adding more oil as needed, until cooked through, 4-5 minutes on each side. Serve while hot.
