I've done a salmon filet in foil, and have had good results on the BBQ with it. I've also done veggies of all kinds in foil as well. But what I've found is that you have to have a proper BBQ to cook it properly. Hubby acquired a large grill, and I find that things in foil need longer to cook, and never build up enough heat inside them to cook properly. Have a great day everyone!
