For the very best outcomes, select one “star” vegetable and not more than 3 supporting ones to forestall the flavors from getting muddy—go inexperienced with a mix of broccoli stems, cauliflower leaves and core, wilted kale and spinach, or get a beta carotene increase with leftover winter squash, wrinkly carrots and a parsnip. The addition of potato (maybe an outdated one which’s rising roots?) and a scoop of oats give the soup an opulent mouthfeel with out cream, whereas lemon juice brightens the flavour.
