In a small mixing bowl, combine all the seasonings.
2 teaspoons guajillo chile powder, 1 teaspoon paprika, 1/2 teaspoon allspice, 1/2 teaspoon cinnamon, 1 teaspoon kosher salt, 1 teaspoon black pepper
In a 6-quart slow cooker, add the garlic, tomatoes, onions, and liquids. Stir in the seasonings.
2 teaspoons dried Mexican Oregano, 6 cloves fresh garlic, 1 cup crushed tomatoes, 1 cup white onion, 2 tablespoons white vinegar, 4 cups beef broth
Place the chuck roast into the crock, turning to coat it in the tomato mixture.
4 lbs beef chuck roast
Cover and set the crockpot to LOW for 8 hours or HIGH for 6 hours.
Once ready, transfer the roast to a cutting board and use two forks to pull it apart.
With the meat still on the cutting board, use an immersion blender to puree the cooking liquid to make a smooth sauce (optional). Remove about 1 cup of liquid from the crockpot and place it into a shallow square baking dish.
Return the shredded beef to the crockpot and toss the beef to coat it with the remaining liquid.
Heat a large skillet or griddle to medium high heat. Lightly spray the surface with cooking spray. Dip a tortilla into the liquid until coated on both sides. Toast the tortilla 1-2 minutes until golden brown.
