Wash the asparagus, cut off the woody ends and cut the asparagus spears in half. Wash and halve the tomatoes. Wash the garlic bulb, cut crosswise into approx. 1 cm wide slices. Peel onions and cut them into slices.
Wash the rosemary and shake dry.
Preheat oven (electric cooker: 200 °C/recirculating air: 175 °C/gas: see manufacturer). Rinse meat and pat dry. Cut the fillets with the skin from the bone, season with salt and pepper.
Brush a frying pan or the fat pan with some oil. Spread the meat, garlic, onions and rosemary in the pan. Drizzle with 2 tablespoons of oil. Fry in a hot oven for about 40 minutes.
After about 15 minutes add asparagus and cherry tomatoes. Pour on the wine. Season with salt and pepper. Ciabatta or roast potatoes taste good with it.
