What to do when you hate the cooking of a family member and you just cant say anything?

my husband and his family were all born and raised in cameroon. my husband and i have been staying with his family for almost 2 weeks and i hate the food. im prego so even just the smell makes me run and hide to vomit. even b4 i was prego i could barely stomach it. my husband calls me inconsiderate because i prefer to eat a ham sandwich every day than tough out the horrible cuisines in front of me. now, while he is gone to afgan next month i will live out the rest of my pregnancy with his fam. bc they are closer than mine. i and my unborn child cannot survive off ham n cheese for another 5 months. what can i do?! every night there is something new and even more gruesome. i honestly wish i was capable of preparing myself for the rest of this pregnancy alone. but i know that wont happen. i dont want to offend them.
