Cut up the chuck into bitesize pieces. Place in a pan, sprinkle with salt and pepper, and sauté.
Place the seared beef in the crockpot. Add garlic, cumin, oregano, ancho Chile pepper, cloves, chipotle adobo sauce, cinnamon, and beef broth. Cook on low for 6-8 hours.
Use finished beef in whatever dish you would like—burritos, quesadillas, salad, anything! Here, we have it placed on tostada shells. Add some seasonal fruit for a refreshing salsa and some queso fresco for that briny, creamy bite that balances out the heat!
