Pre heat oven to 300.
On a flat plate mix olive oil, paprika, chili powder, salt and pepper. Cut ribs into thirds.
Heat Dutch oven on the stove top. Dredge ribs in olive oil mixture and brown on high heat in the Dutch oven, about 5 minutes total.
Meanwhile in a small bowl place beef stock, soy sauce, mirin, rice vinegar and Splenda Brown Sugar mix.
Add garlic and ginger to the Dutch oven, stir and let cook for 1 minute. Add stock mixture, stir and place in oven. Cook for 2 hours, covered.
Depending on the ribs, there may be excess fat to skim off. If you have time, remove the meat and let the sauce chill in the refrigerator until fat solidifies enough to easily remove, or let rest overnight.
Warm meat and sauce before serving, either in pieces or shredded.
Remove beef and plate on Napa Cabbage alongside any other garnishes. Drizzle a bit of sauce and serve the remainder on the side.
Can also be served as a wrap in butter lettuce leaves.
