Marinade overnight or just rub into the roast and cook immediately.
In a large skillet heat 1 tsp olive oil add roast and brown on each side.
Add 1 cup of bone broth to an Instant Pot or Crock Pot, place roast inside and slow cook.
For Crockpot set on low for 8 hours or high for 6 hours.

The roast will shred apart very easily with tongs when done. Shred roast separating meat from fat.
