Wash potatoes thoroughly and cook in boiling water for 18-20 minutes. Drain, rinse and drain well. Soak bread in water. Clean, wash and slice the zucchini.
Peel and finely chop the onion. Squeeze the bread well. Put minced meat, egg, onion, bread, 1 teaspoon salt, pepper, cinnamon and cumin in a bowl and knead well. Form 8 oval flat meatballs from the minced meat mixture.
Grill the meatballs for 4-6 minutes on each side. Wash thyme, shake dry and pluck leaves from the stalks. Peel garlic and chop very finely. Melt the butter in a pan and fry the potatoes for 5-6 minutes over a low to medium heat, turning them over.
After half the frying time, add the garlic. Season with salt. Heat the oil in a large pan and fry the courgettes for 4-5 minutes while turning. Season with salt and pepper, add thyme.
Arrange meatballs, potatoes and courgettes. Crème fraîche tastes good with it.
