Notes
Make sure to rinse the pasta quickly after cooking and before combining with the rest of the ingredients - this cools it down quickly and avoids overcooking.
Drain the pasta well before adding in the rest of the ingredients so the creamy dressing does not get diluted down.
If not serving straight away keep it chilled and mix every so often for the flavors to infuse.
For the Instant Pot version - you really do want to keep the time under pressure to 4 minutes, any longer will likely turn the pasta to mush.
Cook time does not include the time it takes for the Instant Pot to come up to pressure or for the pressure to release.
Store - in an airtight container inside the fridge for 3 days.
