Mix the olive oil, thyme, rosemary and garlic and soak the lamb fillets for 1 hour.
Beans:
Cut the bacon or Wammerl into fine strips. Peel and dice the onion and garlic cloves. Drain the beans well.
Heat the olive oil in a pan and fry the bacon or Wammerl with onions and garlic in it. Add the beans and fry them too. Season with salt, pepper and thyme.
Put the beans in a bowl and keep warm.
Now salt and pepper the marinated lamb fillets and fry for 3 to 5 minutes on each side, seasoning with a little salt and pepper if necessary.
Serve the fillets with the beans and garnish with parsley.
