Heat the lard/tallow or oil-butter blend in a large Dutch oven over medium high heat.
Meanwhile, place the flour in a gallon size zipper storage bag or large paper sack with a few generous pinches of sea salt and black pepper.
Season the stew meat liberally with sea salt and black pepper. Drop a handful of meat pieces at a time into the bag of flour, and give it a good shake until well coated. Use clean hands to shake excess flour off of the meat before transferring to the cooking pot. Repeat until all the beef is coated and in the pot. Discard the remainder of the bag of seasoned flour.
Allow the meat to brown, turning so all sides are cooked evenly. This should take 6-8 minutes.
While the meat is browning, chop the onions and celery, then peel and slice the carrots. Set aside.
Once the beef has browned, use tongs to transfer meat to a plate. Turn the heat down to medium and add red wine (or additional beef stock/broth) to the pot, stirring constantly with a wooden spoon for about 2 minutes to deglaze. (Mine never fully deglazes but that's fine.)
Add onions, carrots, and celery to the Dutch oven and cook, stirring often, until onions begin to turn translucent and carrots and celery are al dente.
Add the garlic and cook another 1-2 minutes, until fragrant.
Scrub the potatoes, then quarter and slice them. Cut the green beans into 1" pieces.
Add the potatoes, green beans, beef stock, Worcestershire, bay leaves, salt, pepper, paprika, and oregano stirring to mix. Return the beef to the pot. Turn heat down to low, cover, and allow to simmer until all vegetables are fork tender, but not too soft (25-35 minutes).
Season with additional salt and pepper if needed, then top with chopped fresh parsley before serving.
