I made this tonight on our charcoal grill. The recipe didn't state how exactly to put the sliced zucchini on, so I put some in a cast iron skillet with some olive oil in it and some in an aluminum foil packet. I didn't bother to brush the ones in the aluminum foil half way through. I think with the leftovers I will put cheese over the top. I think it would have added to this and tamed the sour [filtered] down. I also didn't use the hot sauce.
