Heat the olive oil in a large Dutch oven over medium-high heat. Trim the outside fat off the chuck roast.
Season the chuck roast evenly with cumin, chili powder, paprika, oregano, coriander, garlic powder, sea salt, and freshly cracked pepper on both sides of the roast. Side Note: I don't measure the seasonings; I just sprinkle the roast evenly with each spice.
Place the beef in the hot Dutch oven for 2-3 minutes on each side to sear the meat.
Add the beef broth, whole green chiles, jalapeno, cilantro, and minced garlic.
Place the lid on the Dutch oven and place it into the oven for 2-3 hours, making sure to check each hour to make sure you don't need to add more broth.
The beef is done when the meat is tender and shreds easily with a fork. Carefully, remove any fat that you see in the beef, then shred the beef using a fork.
Place the tortillas on a damp cloth and microwave for 20 seconds to warm up.
Spread some warm refried beans down the center of the tortilla, then add some shredded beef, lettuce, cheddar cheese, tomatoes, green onions, and cilantro.
