It was one of the handouts from the past Advanced Study Weekend.
Go to the ASW page:
https://www.drmcdougall.com/health/programs/advanced-study-weekend/and you'll find the Weekend Speaker Handouts link:
https://www.drmcdougall.com/health/programs/advanced-study-weekend/asw-speaker-handouts/On that page, you'll find these handouts from Mary:
Stocking Your Kitchen
McDougall Weekly Meal Planner
Low Fat Vegan Websites
The first one tells you what to keep on hand, what appliances and utensils will come in handy, cooking charts for beans and grains, etc., and a few lists of Mary's favorite meals and recipes and where to find them.
The second is just a blank weekly calendar you can fill in with what meals you plan on making.
The third is the one page list of websites that you're looking for, taken from The Healthiest Diet on the Planet book.
