First fry the minced meat in hot oil. Then add the onion, sweat with it and finally mix in the garlic. Put everything in the CP - the excess fat can stay in the pan. Now mix in the remaining ingredients well. Cover. Cooking time: approx. 6 - 8 hours on the lowest setting (low). Stir well and season to taste if necessary. Serve on the hamburger bun.
Potato salad with mayonnaise is a particularly good side dish.
