I use the heck out of my Instant pot for lots of things:
Rice, quinoa, millet and other grains. We've dialed in the liquid to grain ratio so we end up with perfectly fluffy grains every time with no monitoring.
Batches of boiled eggs that are easy to peel.
"Pickled" beets for my salads. (Peel and cube, toss in the vinegar and seasonings, cook under pressure 7 minutes, perfect!)
I gave away our big crock pot because we use dutch ovens or clay pots for most true slow-cooking anyway and hadn't used the darned thing in over 5 years.
