Heat the oil in a large pot over medium heat. Once hot, add the onion, sweet potato, and bell pepper and sauté until slightly softened, about 4-5 minutes.
Add the garlic, ginger, curry powder, red pepper flakes, and salt and cook for 1 minute, stirring until fragrant.
Add the coconut aminos, broth, and coconut milk and stir to scrape up any browned bits on the bottom of the pot. Add the black eyed peas and bring to a boil over medium-high heat. Reduce the heat to low to maintain a simmer and cook (uncovered), stirring occasionally, until the black eyed peas are tender, about 30-40 minutes (see notes if using soaked or canned black eyed peas).
Once the black eyed peas are tender, stir in the kale and cook until wilted, about 5-10 minutes. Add the lime juice and adjust as needed, adding more coconut aminos for depth of flavor, salt to taste, and/or red pepper flakes for heat.
This soup is delicious on its own or paired with rice, cornbread, or toasted bread. Garnish with fresh cilantro, if desired. Any leftover soup will keep in the refrigerator for 3-4 days or in the freezer for 1 month (or longer). Reheat in a saucepan on the stovetop over medium heat until warmed through.
Notes
*We love the firmer texture of Japanese sweet potato in this recipe, but you can use any type of sweet potato. If using another type of sweet potato and you want it to have a firmer texture, we suggest adding it after the black eyed peas have been cooking for ~10 minutes. *Freshly grated ginger is better than freshly minced ginger in this recipe because it gives the broth a more even and potent ginger flavor. If using minced ginger, use at least double the amount. *If not vegan, chicken broth would also work well in this recipe. *If using canned black eyed peas, use half the amount of broth and cook for ~15-20 minutes (after bringing to a simmer) to allow the flavors of the soup to develop. *If using soaked black eyed peas, use 3/4 the amount of broth and cook for ~20-25 minutes (after bringing to a simmer), or until tender. *We also tested with collard greens but preferred the texture and vibrant color of kale in this recipe. *Nutrition information is a rough estimate calculated with olive oil and without optional ingredients. *Loosely inspired by Indian curries, Turnip Vegan’s Curry Black Eyed Pea Bowl, and our Smoky Instant Pot Black Eyed Peas & Greens.
