To kick off this delightful recipe, let's prepare the finger-licking BBQ sauce that sets Isley's chipped ham BBQ sandwich apart from the rest.

In a saucepan, combine the ketchup, water, sweet pickle relish, brown sugar, cider vinegar, Worcestershire sauce, liquid smoke flavoring, ground cinnamon, ground black pepper, and garlic salt.

Stir well to ensure all the ingredients are thoroughly mixed.

Set the saucepan on medium heat and bring the mixture to a gentle boil.

Reduce the heat to low and let the sauce simmer for about 15 minutes, allowing the flavors to meld together perfectly.

Once the sauce has thickened slightly, remove it from the heat and set it aside.

Isley's chipped ham is the star of this sandwich, and it's what gives it that unique taste. If you can't find pre-chipped ham, you can use thinly sliced ham and chop it into small pieces.

In a large skillet, heat a little oil over medium-high heat.

Add the chipped ham to the skillet and cook it for 3-4 minutes, stirring occasionally until it's heated through and slightly browned.

Now comes the fun part - putting it all together!

Take a hamburger bun and open it up.

Generously spoon the prepared chipped ham onto the bottom half of the bun.

Drizzle a generous amount of the homemade BBQ sauce over the ham.

Top it off with the other half of the hamburger bun, and your Isley's Pittsburgh Chipped Ham Barbecue Sandwich is ready to be devoured!
