You can cook this dish in the pressure cooker; once stew meat is cooked, transfer it to another bowl. Add oil to the pressure cooker, add tomato paste, pepper paste, onions and sauté for a couple of minutes until you have a beautiful red and vibrant sauce. Add your freshly cut fava beans, add beef stock, stew meat, and pressure cook on high for 10 minutes. Lastly, sauté finely chopped garlic and add it to your stew before serving.
