For the burger cream, peel garlic and chop very finely. Mix mayonnaise, sour cream, milk and garlic. Season with salt and pepper. Peel onions and cut into fine rings. Clean, wash and drain the salad well. Wash and slice the tomatoes
Cut open the buns. Heat 2 tablespoons of oil in a large frying pan. Place 4 halves of the rolls in the pan with the cut surfaces facing downwards, fry briefly in the pan, remove. Proceed in the same way with the remaining roll halves
Put salami slices in two portions in the hot pan, leave them crisp, take them out. Wash the meat, dab dry. Put 2-3 tablespoons of oil into the pan, fry the meat for about 2 minutes on each side, season with salt and pepper
Remove the escalopes from the pan, place them on a baking tray lined with baking paper, spread cheese evenly on the escalopes. Bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for 6-8 minutes
In the meantime, fry the tomato slices briefly while turning them in the pan, season with salt and pepper. Spread the cut surfaces of the rolls with garlic cream. Cover the halves with lettuce, escalope, tomato slices, onions and salami. Spread the rest of the garlic cream in between. Put the lid on and arrange the burgers on plates
