I love the italian dressing marinated veggies on the grill.
I found a recipe for Bourbon Porkloin on SparkRecipes that you grill. It is SO GOOD--even though I make it w/o the bourbon.
You marinate it all day. On the grill you sear the outside, then let it cook 15-20 minutes.
You can also do PIZZA on the grill.
Shape a 6" size crust, cover both sides in olive oil (or spray w/ olive oil cooking spray) slap it on a med/med-high grill (indirect flames is best) for 1-2 minutes until it starts to get puffy and soft looking. Flip over for another minute. You can then add the sauce and toppings then but I find it easier to remove the crust, do the toppings then put it back on the grill. Shut the lid until the cheese is bubbly. YUM!
