Is a vegan diet more or less expensive than a non-vegetarian diet?

It’s hard to make a definitive comparison since there is enormous variation in the cost and quality of the foods we eat. But generally, a cheap vegan diet will be less expensive (and much healthier) than a cheap omnivorous diet. and even an extravagant vegan diet will never be as expensive as a diet based on high-priced meats and cheeses produced with the best animal welfare.
