"Baking" on the Gas Grill

Have you ever "baked" on your gas grill? Pictured above are stuffed shells. I defrosted them in the microwave in the sauce for about 3 minutes while I preheated the grill, all 3 burners turned to the lowest. I topped it off with shredded mozerella cheese and drizzled a little olive oil on the cheese to keep it from browning before the shells were done. I put a piece of foil under the oven proof dish. It took around 25 minutes (uncovered) with the grill lid closed. The last 5 - 7 mintues or so I put the partially defrosted garlic sticks on the top rack.
I've also done meatloaf and baked ziti this way using a Corningware rectangular dish.
