1. Process potatoes and onion in a food processer using the grater/kugel blade.
2. Transfer to a large bowl and add eggs, beef, salt, and pepper. Mix until well combined. (It will be easier to do this if the meat is room temperature.)
3. Heat a large, nonstick frying pan with oil and place large spoonfuls of batter into the hot oil. Fry over medium-high heat for about four minutes on each side, or until latkes are well-browned and meat is cooked through. Remove to a serving dish and continue with the remainder of the latke batter.
