Cauliflower and hamburger
Take out the cauliflower mixture from the fridge and pour it into a large pot. Little by little add either coconut milk or other dairy-free milk, until reaching a quite thick, creamy consistency. Use water instead if you want a lighter result. Heat up the soup on the stove and try it for salt and pepper.
Heat up the leftover hamburger in the microwave oven. Subsequently, cut it up in 1/2 inch / 1 cm cubes. Pour soup into bowls, top with hamburger croutons and serve with salty crackers.
