Begin by seasoning the beef with salt and pepper and set in the crock-pot. Then thinly slice the onions and garlic. Toss those into the crock-pot with the beef.
Lastly, in a small bowl mix the beef broth, vinegar, and dried oregano. Pour this mixture over the beef and let it cook in the crock-pot for about 8 hours on low.
Remove once tender and cooked thoroughly. Enjoy.
