Sounds quite similar to the one i had it's one we get called Chicago town - it had quite a wide crust and it's sooo tasty! My friend&me had it between us at my mum's place - we sat down to watch I'm a celeb together!
After much deliberating, i'm having a frozen mac&cheese it's quite good though as i've ate it before going to have salad with it as i've not ate a really healthy meal for about a week
