Hi Vicki Nist. You may want to take a look at the two videos by Sue Mah. Although there may not be specific lunch plans, she has some good suggestions on prepping beforehand.
One thing that has really helped me is to bring leftovers for lunch. I've made a habit of making larger quantities of healthy dinners, and then packing my lunch with these leftovers. I then know exactly what I'm eating and these are easy to pack lunches.
Hope this helps!
