It's a rainy summer's day, soup was a great idea. I love making this because it's pretty quick for homemade and it strikes a good balance for adults and kids. All depending on who your audience is, choose a mild or spicy chorizo. I haven't made this without using the immersion blender to mix it up. I'm sure it would be fine, I would be tempted to cut things quite a bit smaller if that were the case, and maybe not preboil the potatoes. The original recipe called for kale, but to please all palates I have subbed carrots. You could sub a wide variety of complimentary veg such as spinach or another leafy green. Something with a pop of colour.
