i have and it doesn't always work so well. freezing the broth is okay, but the veggies often defrost watery. i don't do it anymore. oh, chili is okay, but you have to add some liquid back. stew, the potatoes break down. it's different every time, and that's with a stand-up freezer. anyway, that's what i've found.
years ago i used to can (and can and can and can) and i separated the broth from the 'things'. i canned the broth in one jar and the veggies in another and so on. that way, the veggies weren't as waterlogged.
since it's the broth that takes the time, i would just freeze that, and throw in some veggies later.
