We’re pretty poorly adapted to be herbivores. We can’t eat most plants at all, and we can’t eat most parts of most plants we do eat; because we can’t digest cellulose. Some staple foods require cooking; potatoes and beans for example. Many other plants, like spinach, are much easier to digest when cooked.
