It’s hard to imagine an easier meal than this Instant Pot version of the take-out classic. Just mx the sauce in the cooker, then layer the noodles and frozen vegetables as directed in and onto the sauce. The machine doesn’t really even come up to high pressure. When the float valve or pin rises to lock the lid onto the pot, turn it off and set it aside. Don’t leave the pot unattended while it’s coming to pressure. Pay attention to the cues in the instructions below.
