Preheat oven to 325°F.
In a bowl, whisk coconut aminos (or tamari/soy), miso, honey, ginger, orange zest, rice wine vinegar and orange juice.
Place chuck roast in a Dutch oven. Pour the marinade over the top.
Add beef broth around the roast. Cover tightly.
Bake for 3–3.5 hours, until the meat begins to shred.
Uncover and bake 30 minutes more to thicken the sauce.
Shred, toss in the juices, and serve warm.
