I've been wanting to try this for some time now and since the grill was hot from the bread it was a good time to do it.
Cut the Vidalia onion into quarters but not all the way through. Sprinkled with granulated garlic, pepper and added a dab of butter.
Set the onion on a piece of foil and added 3 T of cabernet.
Carefully wrapped the foil around it and set it on the 350F grill.
I also have a spaghetti squash on the grill.
The only problem is I am hungry now. A friend had suggested that I drizzle some maple syrup over that grape-nut ice cream, well, what better time;)
That was a great idea and I'll do it again.
