Can I use ground beef meatballs in stews like Boeuf Bourgogne?
It would be a different  dish, but that's no reason not to try it. Unless they're very picky, I'd  make it as a family meal first  before trying it on anyone else. You may need to make some adjustments. I suggest  browning the meatballs first then not cooking them for as long in the stew, in the hopes that they don't fall apart. The rest of the ingredients may still need a long cooking time, so you might want to add the browned meatballs  partway through cooking if you cook the stew in an oven or on top of the stove. A slow cooker is much gentler and shouldn't be opened during  cooking, so I'd put them in at the beginning as normal  in that case.
