Start by rinsing your pasta under cold water to get rid of any dust or starch. It helps things cook better in the pressure cooker.
Add your pasta to the pot with just enough water for about an inch above the pasta. You need that broth depth to keep it from drying out or sticking.
Seal the lid and check the sealing ring is snug in place. You don't want any leaks messing up the pressure.
Turn the pressure cooker on to high pressure and wait for the float valve to fully pop up. That valve is your cooking buddy, letting you know pressure's built.
Cook the pasta for just a couple minutes more than al dente, usually 4-5 minutes for rotini, depending on your cooker.
Once the timer's up, do a slow release. That means letting the pressure bubble down gently so the pasta stays tender but not mushy.
Open the lid carefully, stir the pasta, then drain off any extra water. Toss in your veggies, olives, cheese, herbs, and dressing while the pasta is still warm. This helps all those flavors slide together real nice.
