what kind of stuff to eat????

Im really picky about food. I also have crohns disease which means I cant eat somethings. I cant have a lot of salad becuse of the lettuce. Basically I cant have anything that doesnt digest. or that is harder to digest than normal. But I need some help finding foods that fill you up and are tasty yet fit for my calories. im on a 1200 calorie diet plan.. anyone know of some good food?? I am not that big of a fruit person either... but i eat them. and im thinking more of stuff for dinner than snack food..
