Here is my entry for Tami's one off blog event, the soup challenge. I'm a bit like Tami's Mum in that nothing is ever written down, I don't measure ingredients and I use whatever is around at the time.
My veggie man at the market did not have any watercress this week and suggested I try Chinese water spinach in its place. There were a couple of zucchini rolling around in the fridge so I added those as well.
When making soup I always start with softening an onion and a clove of garlic. Then I add whatever vegetables I'm using. Today it was water spinach and zucchini. Because I was using veggies that would make a thin soup I added a couple of cubed potatoes as a thickener. Add as much salt as you need to. Cover with water or stock and boil briskly until vegetables are soft. Cool and then blend until smooth. Quantities will vary depending on how much soup you want.
Today I served it decorated with a little yogurt some basil leaves and a peppadew.
