Shredded Beef Quesadillas

Steps

1. Place the meat and bones (if using) in a pot with the onion, garlic, and bay leaf. Cover with 2 cups of water and cook until the meat is tender (about 30 minutes in an Instant Pot).
2. Let the meat cool, then shred it. Discard the bones, mix the marrow into the meat, season with salt, and set aside.
3. Mix the masa harina with the water to form a soft dough, adding more water if needed. Divide into 4 large balls.
4. Roll each ball into a log, then press between two plastic sheets using a tortilla press or glass pie dish to form a large oblong tortilla.
5. Cook each tortilla on a preheated griddle, turning twice until cooked through.
6. Stuff the cooked tortilla with shredded cheese and meat, then top with lettuce, cream, and additional cheese.
