Prep the ingredients.
Heat a large pot over medium-high heat and add oil. Sauté the chopped onions and tomatoes over medium heat until the onions are translucent and seared very well. The tomatoes will slightly caramelize and you will see dark searing and that is good.
2 Tomatoes, 1 Yellow Onion, whole, 1 ½ tbsp oil
Add the vegetable broth and water to the pot. Stir well.
5 cups Vegetable Broth, 2 cups Water
Pour in the vegan fish sauce and stir to combine.Bring the broth to a gentle boil, then reduce the heat to a low simmer.If using vegetable bouillon, stir it into the broth. 1 tbsp Vegan Fish Sauce
Add the sliced yellow sweet potato to the pot. Simmer for 5 minutes.
1 Japanese Eggplant, medium, 2 cups Yellow Sweet Potato, Okra - optional
Use the skimmer and remove some the onions and tomatoes. They were meant to flavor the soup, and you can take at least half of the onion and tomato out for a smoother soup.
Then add the Japanese eggplant. If you are adding okra, put it in the soup at this time.
Wait for the eggplant to turn more brown and tender, then add the green beans and low simmer until they are cooked, but crisp.If you choose to add leafy greens, do it towards the very end. 2 cups Green Beans, Bok Choy or Spinach - optional
Skim the top of the soup as needed.
Ladle the soup into bowls and gently add the soft tofu into the plated bowls of soup. Enjoy with lemon or calamansi on the side.
