Wash the leafy greens thoroughly and chop them into bite-sized pieces. Set aside.
In a large pot, heat the vegetable oil or coconut oil over medium heat.
Add the chopped onion and sauté until translucent, about 5 minutes.
Add the minced garlic and grated fresh ginger (if using) and cook for another minute until fragrant.
Stir in the chopped tomato and cook until it begins to soften, about 3-4 minutes.
Add the chopped leafy greens to the pot and stir to combine with the aromatics.
Pour in the water or vegetable broth and bring to a simmer.
Add the salt, black pepper, and ground nutmeg (if using).
Reduce the heat to low, cover, and let the soup simmer for about 15-20 minutes, or until the greens are tender and the flavors are well melded.
Ladle the bouyon brede into bowls.
Garnish with fresh chopped cilantro or parsley.
Enjoy your meal!
