Spaghetti sauce, chili, pulled pork, chicken for soup, bean soup, beef stew.
Meat works well if you don't have to worry about the texture like in chicken salad or pulled pork. I tried ribs and they tasted great but the texture was off until I stuck them in the oven for 20 minutes to crisp up.
The instant pot is especially good for broth. Drop a whole chicken in, add a cup of water and seasoning,cook for 35 minutes. Pull out the chicken and use it for chicken salad. Throw in some noodles and veges and cook for 10 minutes more for some great soup.
Sometimes I throw in 6 chicken breasts, cook them, then refrigerate them. I use them during the week for various meals after slicing them and throwing them in the frying pan to brown: tacos, Caesar salad, fajitas, chicken Alfredo, etc.
Good luck! It makes cooking easier but only makes some things better.
