Wash the meat, dab dry and cut into pieces. Heat oil in a pan and fry the meat in it at medium heat until golden brown all around. Season with salt and pepper. In the meantime, clean, wash and slice the fennel.
Remove the meat and sauté the fennel slices in the cooking fat. Deglaze with wine and stew for about 5 minutes. Add sauce, stir and bring to the boil. Add meat and olives and heat up again briefly.
Arrange on a plate and serve sprinkled with red pepper and garnished with fennel green as desired.
