frozen food after WLS
I have done the atkins meals low in carbs but high in fat and high in protein which is good! I also have done jimmy dean flatbread sandwiches which have like 12g protein something like that.. otherwise an easy recipe is mini egg quiches.. mix any meat u want, veggies, cheese, and eggs or egg whites poured on top in a muffin tin pan.. they are filling, full of protein, can be suited to however u want them, and u can freeze some!
I'm a teacher too :) I was also worried about what I would bring for lunch but the World According to Eggface Blog was so inspiring. http://theworldaccordingtoeggface.blogspot.de/2010/05/my-bento-lunch.html
I bought myself a bento box and look forward to packing it full of healthy goodies to take with me to school.
Hope this helps :)
