I used Instant pot and put in all ingredients from olive oil to collard greens in instant pot and programmed for soup.
Cook rice according to instruction on package.
Serve stew on top of cooked rice. Garnish with cilantro, peanuts, and lime wedge.
If you do not have a instant pot you can easily adapt this into a soup pan. I would cook onion in olive oil with garlic and ginger and then add spices, tomato paste, sweet potato, peanut butter, broth and water. Let boil and as sweet potato begins to soften add in the collard greens.
