Using the saute mode, heat the electric pressure cooker until “hot.” Add the ground beef and cook until the beef is browned and crumbled. Drain well. Cancel the saute mode.
Return the beef to the pressure cooker and stir in taco seasoning. Add the remaining ingredients in this order: corn, black beans, penne pasta, and salsa. Do not stir.
Place the lid on the electric pressure cooker and set the valve to sealing. Set the pressure cooker to “manual” or “pressure cook” for 5 minutes. Quick release the pressure when the cook cycle is complete.
Stir 2 cups of cheese into the pasta. Top with remaining cheese and place the lid over the pressure cooker just until the cheese melts.
Serve the burrito pasta garnished with tomatoes, avocados, and black olives if desired.
