I like hoagie rolls but there is way too much bread so I hollow them out, and feed that to the birds. I found a beef roast for $1.98/pound and ground it for burger meat, and added Montreal Steak seasoning for flavor. Hollowing out the rolls makes the filling the star of the sandwich, and heating makes the crust crisp and delicious.
The hoagie tops were filled with caramelized onion, while the bottoms filled with blue cheese. Burger meat was shaped in the form of the roll.
I love the way Grill Grates cook - no flare ups, great heat distribution, and perfect grill marks. Definitely one of the best additions to my gas grill.
The roll crust was crisp, the blue cheese melted and giving a perfect complement to the spice in the burger, and the caramelized onion imparting a subtle sweetness that made the sandwich perfect
