Plant-food-oriented nutritional expert Dr. Joel Fuhrman recently posted a “Mexican cauliflower rice and beans” recipe to the Dr. Fuhrman website. The cauliflower in the dish is used as a substitute for the grain, in a way that is reminiscent of pasta made from squash and other vegetables in season this year.
As this site mentioned in this previous post, problems have been reported with arsenic in some rice and rice products, a byproduct of an industrialized world. Dr. Fuhrman’s page for the recipe emphasizes the higher nutrient density afforded by the use of cauliflower instead of a grain, which is always an advantage of such substitutions. (The recipes on Fuhrman’s site are behind a pay wall; this page of consumer advice mentioned last time is not paywalled.)
I have been trying some vegan alternatives to rice-containing Mexican dishes at local restaurants. Various taco dishes that appear from time to time on the specials board at Outdated: An Antique Cafe include crispy and delicious homemade Mexican corn tortillas rather than rice, while people wanting to try avoiding rice at the moment can order the vegan soup or various á la carte items–among other vegan non-rice-containing offerings–at the nonvegetarian Bubby’s Kitchen in Red Hook. (Some other Spanish-speaking countries also have a famous dish called a tortilla.)
Adaptations continue to an evolving situation.
