Place the potato pancakes on a baking tray lined with baking paper. Bake in the preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3) for approx. 20 minutes, turning after approx. 10 minutes
Clean and wash spring onions and cut into slanted rings. Wash and quarter the tomatoes, remove seeds if necessary and dice. Stir the spring onions and tomatoes into the sour cream. Season with salt and pepper if necessary
Clean and wash the peppers and cut them into rings or strips. Wash the salad and drain well. Cover 4 buffers each with lettuce, ham, paprika and sour cream. Place the remaining buffers on top as a lid. Garnish with basil if necessary
This snack can also be prepared for 1 or 2 persons. However, since it is not worth turning on the oven for this, bake buffers with some fat in the pan
