Wash the potatoes thoroughly or scrub them with a vegetable brush. Cover and boil in water for 15-20 minutes. In the meantime peel garlic. Wash oregano and thyme and shake dry. Coarsely chop 2 cloves of garlic, oregano and thyme.
With olives and 3 tablespoons of oil, blend roughly with a hand blender. Season with pepper.
Preheat oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer). Knead minced meat, breadcrumbs, egg and tomato paste. Season with approx. 1 tsp. salt and pepper. Form 4 long, wide sticks (each approx. 5 x 15 cm) from the minced meat mixture.
Heat 2 tablespoons of oil. Brown the chopping sticks on both sides and place them on a baking tray. Spread the olive mixture on top and press down carefully. Bake in a hot oven for 20-25 minutes.
Drain the potatoes and let them cool down a little. For the tzatziki, wash cucumber, grate coarsely and squeeze out well. Chop 1 garlic clove very finely. Mix cucumber, garlic and yoghurt. Season with salt and pepper.
Wash the rosemary, dab dry, remove the needles and chop finely. Press potatoes flat. Heat 1 tablespoon of oil and butter in a large frying pan. Fry the potatoes until golden brown, turning them over. Finally mix rosemary into the potatoes and season with salt.
Arrange chopping sticks, tzatziki and potatoes.
