Lunch time struggle...

I am currently 8 weeks and 4 days along and I find myself struggling to find something that I can actually eat for lunch time. Before I was pregnant I would normally eat a turkey sandwich, some sort of fruit or veggie and a yogurt. Now I don't do turkey due to the nitrates in turkey meat and transfered to peanut butter and jelly. I know I won't be able to keep up until January. Any suggestions of what you ladies are loving would be awesome for a main lunch item. Thanks!
