In a large bowl or ziplock bag add the flour, salt, pepper and oregano. Add the beef stew meat. Stir to coat the meat, or seal and shake the bag to coat the meat.
Set a large skillet on the stove top and set to medium-high heat. When the pan is hot add the oil. Let the oil heat up then add the flour coated stew meat. brown on all sides, no need to cook all the way though. Add the can of beef broth to the pan and using the spatula scrape up the browned bits off the bottom of the pan. After the beef broth comes to a boil, remove from heat and add the meat and sauce to the slow cooker. Add remaining ingredients. Stir.
Cover and cook on LOW for 8 hours without opening the lid during the cooking time.
Discard bay leaf. If desired, degrease the stew. I do this by laying a paper over the stew and lift up, the grease will grab to the paper towel. Serve and enjoy.
