Grumpy and Hungry!!

Jennifer
I'm 10 weeks along and already being treated as having GD due to having issues with my levels prior to pregnancy. Lately I've been so busy with my work and toddler at home, that I don't think too much ahead of what I'll have for lunch or snack throughout the day so I'm constantly hungry at work. I get salads for lunch but that doesn't fill me up and I get bord! 
Any ideas for good lunches during the work day and snack ideas? I really need to start planning ahead or else the sugary, carb cravings are gonna do me in!!
