Peel the skin of lotus root and then cut into thin slices. Soak in clean water for couple of minutes to remove the extra starch and keep the potatoes crispy after cooked.
Bring a pot of water to a boiling and add a small pinch of salt. Cook lotus root slices for 2 minutes. Transfer out and drain.
Prepare another small pan, add 1 tablespoon of cooking oil and fry garlic, red pepper circles, green pepper circles and scallions until aromatic. Place light soy sauce, cumin powder, chili oil, salt, sugar, vinegar, sesame oil and sesame seeds in. Mix well.
Add lotus root slices in. If you love coriander, mix some coriander too.
