Heat 2 tablespoons olive oil in a large pot, add 1 large onion (chopped) and sauté for 3 minutes.Add 3 cloves garlic, 1 inch ginger (both grated), 1 teaspoon cumin, and ¼ teaspoon red pepper flakes and cook 1 more minute.
Add 1½ pounds sweet potatoes (peeled and cut into large bite-size pieces), 4 cups vegetable broth, 1 can (15 ounces) crushed tomatoes, 1 can (15 ounces) chickpeas, 1 teaspoon salt, and ⅛ teaspoon black pepper.
Bring to a boil, then stir in ½ cup peanut butter, lower the heat, and simmer for about 20 minutes, or until the sweet potatoes are fork-tender.
Now stir in the 6 ounces spinach and cook for a few seconds or until they wilt. Taste and adjust for salt.
Top it with a small handful of crushed, toasted, unsalted peanuts, a generous squeeze of lime juice, and some pickled red onions.Serve with brown rice or bread – we recommend warm naan or pita bread to sop up the juices.
