What would a vegetarian find of worthy interest in Jennifer McLagan's Bones: Recipes, History and Lore? She has a vegan recipe for rouille. And what is its function? Let's let her explain:

In France, fish soups are often served with the traditional accompaniments of croutons, grated cheese, and rouille, garlic-and-red-pepper-flavored mayonnaise. Not a big fan of flavored mayonnaise in my soup, I've replaced it with a garlicky sweet potato puree. This delivers the garlic hit as it melts into the soup and thickens it slightly.
