Anything sous vide (if yours has a sous vide button). You can use ziplock bags in Leiu of a vac sealer. Chicken or steak sous vide and then quick seared in a hot pan for color is the best.

Olive Garden style Chicken Gnocchi soup (dozens of copycat recipes online). You can buy pre-packaged gnocchi or make it yourself. Get a loaf of French bread to toast cheap at the grocery store and it’ll blow your mind.

Basically any Chili recipe can be made 5-10x faster pressure cooked. No need to simmer it for hours.

Use it as a rice cooker. Pressure cooked white rice tastes like Chinese restaurant sticky rice and take 10 minutes. Get a box of frozen orange chicken from Costco and you’ve got Orange chicken over rice in about 18 minutes. Or cook some refried beans, brown rice, and fried eggs for a quick breakfast. Nothing beats a salt and pepper runny yolk egg soaked into rice.

Hard boiling eggs you mentioned already, but if you like egg salad it’s a great way to make easy peal boiled eggs for mashing into egg salad in the fridge.

Those are just a few things I use mine for ranging from moderate to simple.
