Saute the stew beef until all sides are browned. It will only take about 2 minutes.
Add the onions, peppers, and garlic allow it to saute for another minute - stirring occasionally.
Add the pasta and top it off with the beef broth.
Gently press down the noodles to submerge them under the broth.
Close the lid and pressure cook on high for 5 minutes.
After the time is up on the Instant Pot, perform a quick release. Slowly and carefully release pressure. Take your time releasing the pressure as it will spew and your meat will be tougher if you rush it.
Open the lid once all pressure is released, add in the cream cheese and the provolone cheese.
Stir until it is all incorporated and serve.
If desired stir mozzarella cheese into the pasta or garnish.
