Notes
Oven Method: Preheat oven to 325°F. Sear the seasoned meat in a large Dutch oven or oven-safe pot on the stove over medium-high heat. Add the remaining ingredients (garlic, onion soup mix, beef broth, coke, soy sauce, and Worcestershire sauce) directly to the pot. Cover with a lid and bake for 3 to 4 hours, or until the roast is completely fork-tender. Slice the meat, return it to the pot with the hot au jus, and proceed with assembling and broiling the sandwiches as directed.Variations:
Make it healthier: serve on a whole wheat bun and leave off the cheese.
Make it "Philly style": add caramelized onions and bell peppers
Add some heat: jalapeños, yellow pepper, diced chilies, or crushed red pepper.
