What a sad state of existence if you think this is true. There are so many incredibly tasty and satiating foods made entirely out of vegetables. Many cultures have a wide range of tasty plant-based foods -- India, Thailand, Japan, Mexico (just to name a few)...have you never had chana masala? Bean tacos? Any of a dozen types of curries? Veggie sushi? Vegetables add so much texture and flavour to dishes (even dishes with meat...).

Vegan food is not just salads and Impossible burgers. Get to an Indian restaurant and pick from any of a half-dozen to a dozen options that are entirely plant-based, and then tell me that there's no vegan food that tastes good and is satiating.
