Finely dice the onion. Clean the broccoli and cut into small florets. Cover and cook in salted boiling water for 5 minutes, remove and drain.
Wash the chicken fillets, pat dry and season with salt, pepper and basil. Wrap the fillets with a slice of bacon each. Heat the oil in a pan and briefly fry the chicken fillets while turning, remove.
Fry the onion in the hot frying fat, dust with flour and sauté briefly. Gradually add red wine, vegetable stock and cream while stirring. Stir in the tomato paste and let the sauce simmer for about 5 minutes. Stir occasionally. Season the sauce again with salt, pepper, sugar and basil.
Put the chicken fillets and broccoli in an ovenproof dish. Pour the sauce over it, sprinkle with cheese and bake in a preheated oven (top / bottom heat: 175 ° C, fan: 150 ° C) covered for 35 - 40 minutes. Cover 10 minutes before the end of the cooking time. Either ribbon noodles or rice are enough as a side dish.
