Re-hydrate soy chunks: Soak soy chunks in hot water for approximately 10 minutes. Once they have softened, drain and rinse with cold water; gently squeeze out excess liquid. Reserve.
Heat olive oil in a large pot over medium-high flame. Once hot, sauté the onion for 3 to 4 minutes, until tender and translucent.
Then, sauté the parsnip and carrots for 3 to 4 minutes more, until they are just tender. Add scallion, garlic, and mushrooms and continue cooking for 2 minutes more, stirring periodically.
Add the other ingredients, including the prepared soy chunks and 1 cup of water; bring it to a simmer. Let your stew simmer, partially covered, for 35 to 40 minutes, until the sauce has slightly thickened and all ingredients are thoroughly cooked.
Garnish with chopped scallions and chili peppers, if desired, and serve hot. Bon appétit!
