Prepare the Beef:

1. Sear the Beef: Heat the olive oil in a large pot over medium-high heat. Season the beef chuck roast with salt and pepper, then brown it on all sides. This step will help lock in the flavor.
2. Sauté the Aromatics: After removing the beef from the pot, add the chopped onion and minced garlic. Sauté until the onions become soft and translucent, about 3-4 minutes.
3. Add the Spices: Stir in the cumin, paprika, chili powder, and bay leaf. Let the spices cook for another 1-2 minutes to bring out their flavors.
4. Deglaze the Pot: Add the beef broth (or water) and Worcestershire sauce, scraping the bottom of the pot to lift any browned bits from the meat. Stir in the tomato paste to blend all the flavors together.
5. Cook the Beef: Return the browned beef to the pot. Cover and let the beef simmer on low heat for about 3 hours or until it’s tender enough to shred with a fork. Alternatively, you can cook the beef in a slow cooker on low for 6-8 hours or use a pressure cooker for a quicker method.

Prepare the Dough for Pulled Beef Ring:

1. Activate the Yeast: In a small bowl, combine the warm water, sugar, and yeast. Stir gently and let it sit for 5-10 minutes until the mixture becomes frothy.
2. Mix the Dough: In a large mixing bowl, combine the flour and salt. Add the yeast mixture and olive oil to the flour mixture and stir until it forms a dough. Knead the dough on a floured surface for about 5-7 minutes until it becomes smooth and elastic.
3. Let it Rise: Place the dough in a greased bowl, cover it with a damp cloth, and let it rise in a warm place for 1-1.5 hours, or until it doubles in size.

Shred the Beef:

1. Shred the Beef: After the beef is cooked and tender, remove it from the pot and let it rest for a few minutes. Use two forks to shred the beef into bite-sized pieces. Discard any excess fat or connective tissue.
2. Mix the Beef with the Sauce: Return the shredded beef to the pot with the cooking liquid, mixing it well to coat the beef in the flavorful sauce. If you prefer a thicker consistency, allow the sauce to reduce by simmering it for a few extra minutes.
3. Add Optional Fillings: If you’re using cheese, chopped bell pepper, or spinach, stir them into the shredded beef mixture.

Assemble the Pulled Beef Ring:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Roll the Dough: Punch down the risen dough and roll it out on a lightly floured surface into a large rectangle, about 12×15 inches.
3. Fill the Dough: Spread the shredded beef mixture evenly across the dough, leaving about 1 inch along the edges. Roll the dough tightly like a jelly roll, then bring the ends together to form a ring shape.
4. Prepare the Baking Pan: Place the beef-filled dough ring on a greased baking sheet or a lined parchment paper.
5. Egg Wash: Beat the egg and brush it over the dough ring to give it a beautiful golden-brown color when baked.

Bake the Pulled Beef Ring:

1. Bake: Place the assembled pulled beef ring in the preheated oven and bake for 25-30 minutes, or until the dough is golden brown and fully cooked.
2. Cool Slightly: Let the ring cool for a few minutes before slicing into it. This will allow the beef filling to set, making it easier to cut and serve.

Serve:

1. Slice and Serve: Cut the pulled beef ring into wedges and serve with a garnish of fresh cilantro or parsley, if desired. Serve it alongside sour cream, a fresh salad, or any dipping sauce of your choice.
