After assembling your ingredients as detailed above, it's time for some simple layering. Start with your onions, the white part of the green onion (if using), and frozen meatballs. Distribute the dry pasta over the top.
Pour over about half the liquid, and pour the seasoning sauce over the top.Rinse out the bowl with the rest of the liquid, and pour that in too. This is roughly the liquid level we're going for: just barely up to the top of the dry pasta. No need to stir, just poke any pieces of pasta that are sticking up down into the liquid.We're aiming for most of the liquid to be absorbed, and the vegetables will contribute a little more as they cook. Add the lightly salted cabbage, and then the frozen veggies to steam on the very top.
Cook on "Manual - High" for 5-7 minutes depending on your pasta. I know these Garofalo bowties need 7 to my taste.
Let the pressure natural release for 10 minutes before opening the valve.
Stir together, and evaluate pasta doneness and the remaining liquid level. If it's too watery and your pasta is not quite there, simmer uncovered for a few minutes until it's good. Also adjust the seasoning as required. I added a little more salt and pepper, but did not need to simmer.NOTE: the pasta will absorb a little more liquid as it rests. Remove from the base, stir in the sesame oil, and let sit covered for 10 minutes before serving.Serve with the green onion tops, and whatever other garnishes you prefer. Enjoy!
