Instructions: In a small mixing bowl, thoroughly combine the onion, celery, ketchup, egg whites, bread crumbs, liquid smoke, and salt and pepper with a whisk.

In a large mixing bowl, pour the sauce over the ground round and thoroughly work the wet ingredients through the meat with freshly cleaned hands.

Spray a large loaf pan with non-stick cooking spray and pre-heat the oven to 325-F degrees.

Bake the meatloaf for about an hour until cooked through. Pour off any excess fat and drippings that formed while baking and let the meatloaf cool until you can readily slice the loaf to finish the feast on the grill.

Prepare your grill for moderate cooking. Place the meatloaf slices on the grill and warm through for about 8 to 10 minutes, making sure to turn the meatloaf slices several times as you go. Serve warm; its great with potato salad.
