Dongbei Di San Xian (地三鲜 — Three Fresh Treasures)
Dongbei region — Heilongjiang, Jilin, Liaoning
Classic Northeastern Chinese stir-fry of three summer vegetables — aubergine (eggplant), potato, and green pepper — each deep-fried separately before combining in a garlic-soy sauce. The name means 'three fresh things from the earth'. Despite its humble ingredients, the preparation is labour-intensive and requires excellent technique.
