Heat avocado oil in a large pot. Sauté onions and garlic until fragrant.
Add the bell pepper, half the green onions, and the tomatoes. Stir and cook over medium heat until the vegetables become soft.
Stir in the tomato paste and cook for 3–5 minutes, until darker and caramelized.
Add the bouillon cube and water, and stir well.
Add the carrots and cabbage. Simmer until the vegetables are mostly tender, about 20 minutes.
Remove the vegetables carefully and set aside.
For the green sauce, blend or mash in a mortar the remaining green onions, parsley, garlic, chives, olive oil, and a little salt. Set aside. Add half of the mixture to the tomato broth.
Add the rinsed rice into the tomato broth. Stir well, cover tightly, and cook on low heat for 20–25 minutes, stirring occasionally to make sure the bottom is not burning, until fluffy and deeply flavorful.
Place the vegetables back in the pot along with the okra during the last 5 minutes to warm through.
Transfer to a serving dish in an inviting and appetizing way by arranging the rice first with vegetables on top. Spoon the extra green sauce over everything.
