In Congo, Saka-Saka refers to cassava leaves.
Thoroughly crush, mash, or grind the greens in a mortar and pestle or with whatever you can improvise. (roll them with a rolling pin, crush them in a heavy bowl with the bottom of a sturdy bottle, etc.)
Bring a large pot of water to a boil; add greens and cook for 30 minutes or more (much more if using cassava leaves).
Add all the remaining ingredients to the greens and bring to a boil, then reduce heat and simmer. Do not stir. Simmer until the water is mostly gone and the greens are cooked to a pulp.
