Lunch?

So, I am 8.5 weeks pregnant and i can't ever think of anything that I want to eat (besides crackers, oatmeal, Cheerios, and chicken noodle soup). I know that I need to be eating healthy and I just can't. I've always been a healthy water but nothing sounds good. Does anyone have suggestions for meals? Specifically lunch because I eat at work and I always just end up eating oatmeal and crackers and then I'm starving! Thanks!
