I have to give up my ATkins Advantage bars for awhile, since I'm not losing anything on Induction and it may be them causing it....

I need quick things I can make and take with me when I'm running....I'm a substitute teacher, and often don't get time to prepare after a phone call from a school....I need something ready to go and portable and easily stored (I never know where the fridge is at whatever school I'm going to!).

Please help. Oh, I love chocolate....so I'd love substitute ideas for that. The bars used to satisfy that urge.....but now, no can do!
