Prep Ingredients: Dice the onion, garlic, bell pepper, jalapeño (if using), and sweet potato. Set aside.
Create Base: In a large pot, heat a little oil over medium heat. Add the onion and sauté for 3-4 minutes until soft. Add garlic, bell pepper, and jalapeño, and cook for another 2 minutes.
Add Sweet Potatoes and Spices: Add the sweet potato cubes, chili powder, cumin, coriander, curry powder, and cayenne pepper. Stir well to coat the veggies.
Incorporate Liquids: Pour in diced tomatoes, vegetable broth, coconut milk, and peanut butter. Stir thoroughly until peanut butter dissolves.
Simmer: Bring the stew to a gentle boil, then reduce heat and let it simmer for 20 minutes, or until sweet potatoes are tender.
Add Chickpeas and Greens: Add chickpeas and greens to the pot. Stir well and cook for an additional 5 minutes until greens are wilted.
Season and Serve: Adjust seasoning with salt and pepper. Serve hot, garnished with fresh cilantro and a squeeze of lime. Pair with rice, quinoa, or crusty bread.
