1. In a bowl, put the finely chopped meat, onion, and carrot, peeled garlic, thyme and bay leaf, pepper, and chopped orange zest.
2. Pour the wine and let marinate for 12 to 24 hours in the refrigerator.
3. The next day, drain the meat and sauté it in a hot skillet with oil, piece by piece, then transfer it to a pressure cooker.
4. Bring the marinade and its ingredients to a boil in the skillet used for the meat for 5 minutes.
5. Pour over the meat, add salt (but not too much as we will add olives at the end of cooking), and add the tomato sauce.
6. Close the pressure cooker and cook for 1 hour and 30 minutes from the rotation of the pressure valve, which should turn at a slow speed (the heat should not be too high to prevent the meat from sticking to the bottom).
7. Let the pressure cooker cool down, then open it and add black olives and 2 tablespoons of olive oil.
