Not liking Any shabbos food is a pretty big margin! Are you a vegetirian? Is it shabbos foods thats the problem or even during the week you dont like most foods? If you like certain foods that you have during the week there is nothing wrong to eat them on shabbos. There is no mitzvah in specificly cholent, chicken soup, gifelte fish, and potato kugel, The mitzvah is busar, dagim and also that there should be chamin – hot food. So if you have foods that you like that fit these critereas its perfectly fine. Otherse if its that you just don’t like most food in general; than there is not much I can help you with.
