I have no doubt that many would struggle with it for many valid reasons.
For a whole lot of people (even people who eat meat), plant based vegetarian food still forms the foundation of their diet, and it's been that way since the dawn of agriculture.
For example, a dish made of legumes, grains, and vegetables flavored with a little bit of meat, while not vegetarian, is still fundamentally plant based. That describes a whole lot of traditional foods the planet over.
