On pressure cookers: in general they are the most helpful for taking a recipe that you would simmer/braise for many hours and shortening the time. If your meat is coming out dry, you may have cooked too long, but more likely it's the wrong cut - stews can work really well.

Other things: it will make a really decent stock in less than an hour. It can do wonders with dry beans. If you want to try again, these guys are mostly pretty reliable as a starting point: https://www.seriouseats.com/pressure-cooker-recipes.
