🥘 Why This Recipe Works
In Malaysia, this vegetable medley is famous as 四大天王 (sì dà tiān wáng, “Four Heavenly Kings”) — the classic quartet of okra, long beans, eggplant and stink beans (petai). 芭樂媽 (Qistin Wong), a Malaysian mum now cooking in Taiwan, swaps in the vegetables that are easy to find abroad and lets a spoonful of sambal do the heavy lifting. Her sambal is a 無五辛 (wú wǔ xīn) version — no onion or garlic — so it stays within traditional Buddhist vegetarian boundaries while keeping all that fiery, fermented depth.
The trick that makes this dish sing: searing the king oyster mushroom caps first until golden brown. Their dense, chewy texture and natural glutamates bloom into something almost seafood-like, standing in for the shrimp that often anchors sambal dishes. The okra and long beans then braise briefly in the spicy sauce, turning silky and deeply flavored instead of raw and grassy.
This version: 8 ingredients, one pan, 15 minutes.
🛒 Ingredients
| Okra (秋葵) | 8–10 pods | Trimmed, sliced into thick coins |
| Long beans (長豆) | 6 stalks | Cut into finger-length pieces |
| King oyster mushroom caps (杏鮑菇頭) | ~150 g | Torn into bite-size pieces |
| Malaysian sambal chili paste (叁巴辣椒) | 2 tbsp | No-onion/no-garlic (無五辛) version |
| Soy sauce (醬油) | 1 tbsp | Light soy |
| Salt (鹽) | ½ tsp | Adjust to taste |
| Water (清水) | 30 ml | For braising |
| Cooking oil (食用油) | 1–2 tbsp | Neutral oil |
👨🍳 Instructions
Step 1: Prep the vegetables
- Trim the stems off the okra and cut each pod into thick coins — the chunky cut keeps them from turning slimy.
- Snap the heads and tails off the long beans and cut them into finger-length segments.
- Tear the king oyster mushroom caps into small, rough pieces by hand; the uneven edges grip the sauce better than knife cuts.
Step 2: Sear the mushroom golden
- Heat the oil in a wok or skillet over medium-high heat.
- Add the mushroom pieces and let them fry undisturbed until deeply golden, then toss and repeat — this builds the “seafood-like” umami.
Step 3: Add the greens
- Tip in the okra and long beans and toss everything over high heat for about a minute.
- Keep them moving so the vegetables pick up the toasted mushroom flavor.
Step 4: Bloom the sambal
- Turn the heat down to low and add the sambal chili paste.
- Stir constantly for about 30 seconds until the paste is fragrant — low heat stops the sambal from scorching and turning bitter.
Step 5: Season and braise
- Splash in the soy sauce, sprinkle over the salt, and turn the heat back up.
- Add the 30 ml of water, cover, and simmer for about 4 minutes until the okra and long beans are tender and the sauce clings to every piece.
Step 6: Serve
- Uncover, give the wok one last toss, and slide everything onto a plate.
- Serve hot over steamed rice — it is a 下飯菜 (rice-scarfing dish) in the best way.
💡 Tips & Substitutions
| Can’t find sambal chili paste? | Use sweet chili sauce, or blend fresh chilies into a paste with a little sugar and lemongrass for a close approximation. |
| Worried about the heat? | Start with 1 tablespoon of sambal and add more at the end; a pinch of sugar balances the spice. |
| Want the true “Four Heavenly Kings”? | Add diced eggplant and stink beans (petai / 臭豆) — they are the other two members of Malaysia’s classic quartet. |
| No king oyster mushroom? | Shimeji, oyster, or shiitake mushrooms all work — just give them the same golden sear. |

Ingredients
Method
- Trim the okra stems and slice each pod into thick coins. Snap the ends off the long beans and cut them into finger-length pieces. Tear the king oyster mushroom caps into small, rough pieces by hand so the uneven edges grip the sauce.
- Heat the oil in a wok or skillet over medium-high heat and fry the mushroom pieces until golden brown on all sides. The golden sear releases a seafood-like umami that stands in for the shrimp usually found in sambal dishes.
- Add the okra and long beans and toss everything over high heat for about a minute so the vegetables pick up the toasted mushroom flavor.
- Turn the heat down to low, add the sambal chili paste and stir constantly for about 30 seconds until fragrant. Low heat prevents the paste from scorching and turning bitter.
- Splash in the soy sauce and sprinkle over the salt, then turn the heat back up. Add 30 ml of water, cover, and simmer for about 4 minutes until the okra and long beans are tender and coated in the sauce.
- Uncover, give the wok one last toss and serve hot over steamed rice. Leftovers keep well and taste even better the next day.
Notes
🌱 Why This Dish
叁巴 (sān bā, sambal) is the beating heart of Malay and Peranakan cooking — a pounded chili condiment that often includes shrimp paste, shallots and lime. In vegan kitchens the shrimp paste is dropped and the heat comes purely from chilies and fermented depth, which is exactly why 芭樂媽’s 無五辛 version fits the Chinese Buddhist table. The nickname 四大天王 borrows the name of the Four Heavenly Kings, the guardian deities who stand at the gates of Buddhist temples — a playful nod that shows how deeply the dish is woven into the region’s Buddhist and vegetarian food culture. In Malaysia and Singapore, okra, long beans, eggplant and stink beans are stir-fried together at home and sold by the scoop at economy-rice stalls (雜飯檔), where monks, office workers and families line up for the same plate. Every home cooks it slightly differently — but the sambal is always the soul.
