This is a good time of year to pick up Corned Beef cheap. You can make all kinds of stuff out of it in an instant pot...like pastrami. https://pressureluckcooking.com/instant-pot-pastrami/  
This guy has a lot of good recipes.  

Instant pots are a time machine for:
Meats
Baked potato
Hard boiled eggs
Chili
Stews
Frozen chicken breasts (just toss them in for 20 min cook time)
Noodle dishes
Desserts
etc, etc, etc...
We use ours a couple of times a week at least!
Bon Appétit!
