Prepare all of your vegetables. Then, take half of the diced onion, leek, green pepper, and minced garlic, and blend it in a food processor. Set it aside.
In a large pot, heat some olive oil over medium heat. Add the other half of the vegetables (onion, leek, green bell pepper, and garlic). You can also add the habanero pepper. Saute the ingredients for 3-5 minutes.
Then, add the vegetable bouillon powder, flour, garlic powder, and powdered nori. Give them a good stir so that all the vegetables are well coated.
Remove the pot from the heat. Now, add the thawed, dried chopped cassava leaves with the red palm oil. Stir them in very well.
Add the blended vegetable mix to the pot as well. Stir it in good.
Finally, add your water. Stir the ingredients very well so that the flavors merge beautifully.
Place the pot back onto medium-high heat. Bring the liquid to a boil. Allow the soup to boil gently for 45 minutes.
After the soup has cooked sufficiently, you can add salt and pepper to taste. You can also adjust the spiciness of the cassava leaf soup.
Leave the soup to simmer for another 10-15 minutes until you don't have any excess water. It should be thick in consistency and have a bright green color.
Serve your stew immediately while it's still hot. It goes amazingly well with plantains, rice, cassava, or fufu.
