This flavorful vegetarian Thai red curry recipe matches sweet potatoes with fresh dandelion greens and asparagus, though you can substitute cauliflower florets, cubed Asian eggplant, squash or carrots. If you’re using cauliflower or eggplant, add them earlier, when the potato is only partially cooked, as they will take longer to cook than asparagus. Classic Thai red curry is flavored with lime leaves and Thai basil. If you find them, use them, but even without them the vegetable curry will still be a knockout.
