As for difficulty cooking things on the grill, just go for it, I've even made bread on the grill. Haven't tried making a pie on it yet, but I see no issues doing so. I grill at least five days a week and I make the whole meal on it, veggies, taters, etc, we eat out at least one, so................
My family are the VIPs in my life so each and every meal gets the VIP treatment, I don't think I could pick which is the best.
So I will go with this, my lady makes the best meat loaf I've ever eaten, I don't have to make it, so it's MY favorite. Sorry, I don't have her recipe. If I ask her for it, then guess who makes it the next time, and yes it would be on the grill, LOL.
