Nutella is the worst stuff ever.
I make myself this sandwich...err wrap at work a lot, I basically ripped it off from some restaurant I ate in Long Boat Key (near Sarasota). Flour tortilla, steamed so it rolls nicely, filled with grilled chicken (usually with just salt and pepper, oregano and thyme), thin sliced tomato, ovoilne ("fresh") mozzarella, prosciutto, red onion, and some pesto (homemade) aioli. It's quite tasty.
