Mix all ingredients and set aside.
Spray bottom of Instant Pot liner with cooking spray. Break spaghetti noodles in half and add in several layers, each layer at right angles to the previous layer. Add water and sauce ingredients to the instant pot. Do not stir but push down or spread out any noodles that are sticking above the sauce. It’s ok for the very top of the noodles to be just even with the liquid. Add carrots and mushrooms in an even layer (as possible) on top of the noodles; try to make sure the noodles are covered as best as possible by the noodle layer.
Make a foil packet for the more delicate vegetables: Place the broccoli and snow peas in the center of a piece of foil. Add a tablespoon of water and fold foil around the vegetables to form a packet, sealing tightly. Place packet on top of carrots and mushrooms.
Seal Instant Pot and set for High Pressure for 5 minutes. (It will take a few minutes to come up to pressure; be patient.) Immediately Quick Release when finished, remove the lid and press the Cancel button and then press the Saute button. The noodles will still be stiff and there will be quite a bit of sauce. Open up the foil packet to determine if vegetables are done to your liking. If they need more time, add them to the Instant Pot to finish off in the next step. Add cooked turkey to the Instant Pot.
As the contents of the Instant Pot comes up to a boil, stir with a large spoon, breaking up any clumps of noodles, making sure to turn over everything that’s at the bottom of the pot. Continue to simmer, gently stirring as needed until the noodles are at the desired doneness and sauce is mostly gone, two to three minutes. The noodles will continue to absorb more of the sauce as they sit. Add in the vegetables from the packet if they haven’t already been added.
Serve immediately, garnished as desired.
Note: This recipe has only been tested in a 6 quart Instant Pot using exactly 8 ounces of noodles (half the box) and the exact amount of liquid. Changing those proportions may change the outcome.
