Season cubed beef with salt and pepper
Heat a large pot or dutch oven on medium high heat, add vegetable oil. Working in batches brown the meat and remove to a plate and repeat.
Add onion and garlic and cook 2-3 minutes. Add in cumin, and oregano and mix. Then add beef back into the pot. Add 2 cups beef broth. Bring to a boil, reduce heat and cook uncovered for 1 hour.
In a saucepan add dried peppers and 4 cups beef broth and bring to a boil reduce heat and let simmer 30 minutes. Remove from heat and let cool.
Once cooled add peppers and juice to a blender or food processor and blend until smooth. If the pepper mixture is chunky push through a mesh strainer to remove any leftover skins.
After the beef has cooked for 1 hour Stir in 1/2 of the pepper puree. And cook uncovered another hour.
Lay a flour tortilla out and place about 2-3 tablespoons of refried beans then place 3-4 tablespoon of the beef. 2 tablespoons of shredded cheese. Roll the tortilla up and place in a baking dish. Top each burrito with 3 tablespoons of the sauce and sprinkle cheese
Bake at 400 degrees for 10 -12 minutes or until cheese is bubbly. Top with your favorite toppings.
