Grassfed Beef Soup Bones

Want to make your own bone broth? It's a little time consuming, but not that hard.

Roast the bones @ 450 F for 30-40 min until deeply browned.
Throw into a pot or slow cooker with some onion, carrots, celery (or whatever veggies need to get used up).
Add salt, pepper, and a dash of vinegar (apple cider vinegar is ideal, but any will do).
Cook for 12-24 hours.
