When short on time, make this favorite German stew in an instant pot. Brown the meats (as in recipe steps 1 & 2 below) using Sauté setting on your instant pot. Add the remaining ingredients (as in recipe steps 3 & 4) and cancel the Sauté setting. Close the lid and turn the venting knob to the sealing position. Change the setting to Manual and cook on high pressure for 10 minutes. Do a quick release or allow the pressure to release naturally.
