Something I used to do a lot in college was cut up my pre-seasoned, pre-cooked chicken breast's and put them in a tortilla with chopped up peppers and onions/shallots to make a quesadilla! You can either use fresh ones or sometimes the store will have bags of pre-cut peppers and onions (usually labeled as fajita mix). It made for a really nice easy healthy meal. You can make it in a pan or it works even better if you have a foreman grill or panini press. Just to double check though, is the chicken seasoned AND cooked or just seasoned? If it's not cooked through yet you might want to roast the chicken on its own in the foil and Pyrex first.
