I love whole30 soup purees. There are so many delicious ones that I have routinely had these for breakfast during past whole30s. You could really eat them for any meal. Well fed by Melissa Joulwan has amazing soups. Also Paleomg.com has my favorite sweet potato soup (savory not sweet). I would see if Whole30/Melissa recommends any egg protein powders for during emergency situations/circumstances.
