Clean, wash and cut the peppers into strips. Clean, wash and cut spring onions into rings. Wash the meat and dab dry. Heat 2 tablespoons of oil in a frying pan. Put 4 minute steaks in the pan and fry on each side for about 1 minute on a high heat.
Season with salt and pepper and remove. Add another 2 tablespoons of oil to the pan, fry the remaining 4 slices of meat in the same way and season. Add the bell peppers to the frying fat and steam for 4-5 minutes, turning them over.
Add spring onions and stew for another 2 minutes. Season with salt, pepper and paprika. Deglaze with stock and tomato sauce, bring to the boil and simmer for about 1 minute. Season with salt, pepper and paprika.
Meanwhile grate the cheese finely. Crumble the chips coarsely. Place the meat side by side in ovenproof flat casseroles or on a baking tray, spread the bell pepper and spring onion vegetables on top. Spread the crisps on top, sprinkle with cheese and bake in a preheated oven (electric cooker: 225 °C/ convection oven: 200 °C/ gas: level 4) for 6-8 minutes.
Remove from the oven and garnish with parsley.
