These mouth-watering Shredded Beef Sandwiches is slow-cooked to perfection by allowing the flavors to mesh together and give caramelized beef shreds. Taste the sweet notes of ketchup, onion, and brown sugar with the tanginess of the mustard and Worcestershire sauce. Sprinkle in some Tabasco sauce, paprika, and chili powder to get that nice, spicy kick and savor a hearty sandwich!
