Got this off the website mentioned above concerning eating low carb/high fat. Thought there could be others who needed a recipe. Note - this is a restaurant sized recipe - so 1/2 or 1/4 the measures.

I'm making a couple roasted chickens this week, so I will have some of this simmering on the stove by the end of the week!
Bone Broth
2 oz roasted garlic (weight)
10 oz roasted red onions (weight)
4.5 gallons water (volume)
22 oz tomato paste (weight)
4 oz cilantro with stems
2 pounds chicken back bones (weight)
16 oz tomato pulp (weight)*
6 oz salt (weight) I would use Celtic Sea Salt or other such salt here
1 oz black pepper (weight)
1 oz olive oil (volume)
Roast onions and garlic in olive oil for approximately 15 to 20 minutes.
Add all ingredients to water, chicken and tomato paste.
Let simmer over medium fire until cooked.
