Cauliflower-Sweet Potato Curry

Heat oil in a large pot over medium. Add onion, garlic, and ginger, season with salt, and cook, stirring occasionally, until onion is tender, 4 to 6 minutes. Add curry paste and cook, stirring, 2 minutes. Add coconut milk and 1 cup water, along with cauliflower and sweet potato. Bring to a boil, then reduce heat to medium-low and partially cover.

Simmer until cauliflower is tender, about 15 minutes. Add zucchini and edamame; return to a simmer, then partially cover and cook until zucchini is tender, 4 to 5 minutes. Stir in spinach and cook, uncovered, until bright green and just wilted, 1 to 2 minutes. Season to taste. Serve over grains, with cilantro and a squeeze of lime.
