We use ours at least once a week:
Rice
Indian dishes (tons of these - lentil dishes, potato/cauliflower, chicken korma, etc.)
Risotto (amazing and super simple - no stirring!)
Sweet potato chili (the sweet potato does not get mushy like in a crockpot)
Shredded chicken for tacos
White chicken chili
Easy lasagna (this is less good than an oven-baked lasagna, but still good and way less time)
We have found food in the instant pot tastes way better than crockpot recipes. It doesn't fill the same need, because you can't set it up in the morning and come home to dinner, but the food tastes better.
I don't really understand the comments about being flavorless. There's a sautee function - if you're cooking meat you should sautee first to brown it and get some flavor in whatever sauce you're making. If you're using garlic, onions, etc. you can easily sautee to create flavor like you would on the stove. I'm sure there are a lot of bad recipes out there on the internet, but if you get a good instant pot cookbook it's a great way to make quick and healthy dinners.
This. I like to saute the meat, onions, garlic and then throw in some broth, vegetables, herbs, salt/pepper, rice or quinoa and then pressurize for 20-30 minutes. It's a lot faster than letting a soup simmer and you get the same depth of flavor you would if you simmered for much longer.
I also use it to cook a whole chicken for chicken salad. Also for apple sauce (which is so much better than anything you can buy). I use it more in the winter because I am making more soups and stews.
