Beef Bone Broth and then Onion Soup

I made the Bone Broth from Balanced Bites:

A package of frozen soup bones (didn't bother to de-frost), a splash of apple cider vinegar, a few grinds of sea salt, and a whole handful of smashed garlic cloves.  Put in a crock-pot on low for 24 hours.  Strain into a bowl, let it cool, and skim the fat layer off the top.

Later the next day:
Take some of the onions from the crockpot onions in Lemon Saffron Chicken, and some of the broth, heat up on the stove and let simmer for 20 minutes.  It's a kind of French Onion Soup, without the cheese and bread.  So, I guess that just makes it plain, old, delicious Onion Soup.
