In a small bowl, combine salt, pepper, thyme and garlic powder. Rub this mixture all over the surface of the meat.
Heat a heavy pan over medium high heat. Add oil and sear meat on all sides, 2-3 minutes per side.
While meat is searing, add coconut aminos, broth, Worcestershire sauce, bay leaf and chopped onion to your crock pot. Stir.
Once meat has browned, remove it from the skillet, and place it in the crock pot. Add 1/2 cup water to the hot skillet and scrape up any browned bits. Add that liquid to the crock pot as well.
Turn meat over a couple times to coat it in the broth mixture.
Place lid on crock pot and cook over low for 6-8 hours, until meat is very tender and comes apart easily with a fork.
Serve meat with broth as is or create a French Dip using your favorite bread, melty cheese and serve the au jus for dipping on the side.
