I agree with the previous reviewer, the time did seem off. I just made one serving but I think 12 minutes of the veggies in the oven would burn it (It took me around 7 minutes). It was really delicious however. I did make a change and used American cheese because I had alot of them in my fridge although I had some swiss cheese spread... Next time I'll try it with the swiss. I also made my own semi italian dressing using a recipe on this site Creamy Italian Dressing I)although I didn't have all the ingredients for this dressing (garlic salt, onion) the sandwich was really tasty none the less. And I actually used a roman meal bread because that's what I bought before! I ate it with a large portion of salad. It was really delicious, I'll make it again with some variations just because I like experimenting.

i'm giving it 4 stars for the proportions & cooking time (which was off), not the taste... that was 5 stars. i used 1/3 lb of Gruyere, 1 zucchini, 1 pepper, and 1 small onion (roasted in the oven about 25 minutes), and this made 3 sandwiches. we also had Annie's shitaki-vinaigrette and used that for a wonderful marinade. YUM!
