Fill your pressure cooker with water and some salt, then toss in your pasta. Follow the package for timing but reduce a little cause the cooker heats up fast.
Seal the lid, let it come to pressure, watch that float valve pop up.
Cook the pasta just until al dente, maybe a hair less to keep it firm after rinsing.
Quickly release pressure using the steam cues, and carefully open the lid when safe.
Drain the pasta in a colander and rinse under cold water to stop the cooking and cool it down.
In a big bowl, add the cooled pasta, mozzarella pearls, tomatoes, and chopped basil.
Pour the balsamic vinaigrette over everything and toss gently so you don’t squish the tomatoes or cheese.
When you serve, drizzle that balsamic glaze on top for a little fancy touch and extra zing.
Notes
Best served fresh, but leftovers can be stored in the fridge for a day or two. Refresh with balsamic vinaigrette before serving.
