Nausea and snacks

Hi all, I’m currently 6 weeks 6 days pregnant and feeling very nauseous. I work a 9 to 5 office job and no one at work currently knows I’m pregnant. I find that I’m feeling nauseous so the thought of food isn’t appealing, but the more hungry I get the worst the sickness gets (luckily I haven’t physically been sick yet). Does anyone have any snack suggestions that will help with the hunger but aren’t too offensive to eat? I’m in the UK but any suggestions are welcome and appreciated.
