fajita seasoning in a pan, with a small chopped onion and thinly slice chicken breast, keep stir frying till it's cooked then bung some grated cheese in and keep stirring it round.
Cut a large foot long break roll in 2 and lightly toast it then put the chicken, onion and cheese mixture onto the bread.
Yummy
It's also just as good if you cook the chicken with a little Garlic powder and mixed herbs or if you really want to push the boat out, make jerk chicken with reggaereggae sauce (very time consuming with all the marinading and slow grilling etc...) and then melt cheese onto that before putting it on your foot long bread.
Even better if you can't be bothered cooking.
