Step 1

Heat oil in a large skillet over medium-high heat. Sprinkle roast with salt and pepper and cook until seared on both sides, about 3 minutes per side.

Step 2

Transfer to a slow cooker.

Step 3

Add onions to the skillet and cook until lightly browned, about 3 minutes.

Step 4

Add onions to crock pot along with remaining 1/2 teaspoon salt, beef broth, Worcestershire sauce, bay leaf, garlic and thyme. Cover and cook on LOW for 9-10 hours.

Step 5

Heat oven to 375 degrees. Cut rolls in half and line insides with cheese slices, using 2 slices per hoagie roll. Place on a baking sheet and bake for about 5 minutes, until cheese is nicely melted.

Step 6

Remove the meat from the crock pot and place in a bowl. Use a fork to shred it.

Step 7

To serve, stuff each hoagie with beef and onions and serve with cooking liquid.
