grilled veggies on bread?

I was working on some photos from this weekend a little earlier when I began to have the biggest hankering for a grilled cheese sandwich. I can't have grilled CHEESE, per se, but I can try something similar, right? And thus, my leftover-grilled-veggies sandwich was born. Alright, it was certainly no grilled cheese (what is, though?) but it was pretty delicious. And it did stop my craving! All that you'll need is veggies in whatever way/shape/form you'll have them, bread, and olive oil. Even before my health kick, I used olive oil instead of butter on my grilled cheeses. It doesn't get as oily and soggy!

The sandwich paired really well with my current favorite snack, Trader Joe's Sweet Potato Tortillas. Sandwiches are just... wow I love them. Always have. Any of you have a favorite sandwich recipe? I'd love to hear it!
