Squeeze the lemon. Dice the smoked bacon and onion, mix with tomato paste, salt, pepper, half of the lemon juice, sugar and cream to a spicy porridge.
Wash the fillets, drizzle with the remaining lemon juice and lightly salt. Spread the porridge on one fillet at a time, put on a second fillet and spread it too. Scatter some breadcrumbs over the fillets. Put on flakes of butter.
Bake in a well-greased grill pan or casserole dish in a preheated oven at approx. 220 ° C (fan oven approx. 200 ° C) for 18 to 25 minutes until crispy.
At the same time, peel the potatoes and cook them in salted water with a bay leaf for about 20 to 30 minutes, depending on the size of the potatoes.
If you like, you can also serve vegetables or green salad.
