I've scrabbled together a pot roast recipe I follow loosely that gets praised every time I make it. I get a chuck roast (or something similar), evenly coat in salt and pepper to taste, saute it in the insta pot(about 6-7 minutes each side to brown it), deglaze with red wine vinegar, then put in half a small package of carrots and little red potatoes(onions can be added but nobody likes them here). I also add 2-3 pepperoncinis on this bottom layer, then I put the roast back in, put the rest of the carrots/potatoes/another couple of pepperoncinis on top and around. Then I add a cup of water and beef bullion, and set the pressure cook feature to around 1 hour 10 minutes or so. I use the keep-warm mode and while it's ready to go once the main pressure is done, it just gets better over time (and you can do it before leaving for work and come home to lunch or supper already waiting). I'm really lazy when it comes to cooking, but this has been easy, fast and delicious (plus leftovers!).
An even easier thing is shredded BBQ chicken. They can even be frozen and it's done in an hour. Would write the recipe but leaving for lunch now.
