In a bowl, mix together all stuffing ingredients until well blended. Light dust pepper pieces, eggplant ovals and mushroom caps with cornstarch to cover insides. Fill each piece of vegetable with about 1 tbsp stuffing, mounding it slightly. Dust each piece with additional cornstarch to coat lightly.
Heat oil in a non-stick frying pan. Starting with stuffing side, pan sear vegetables until golden on both sides, about 3 – 4 minutes. When done, remove from pan and keep warm.
Prepare sauce: In same frying pan, add oil to sauté garlic, ginger and black beans. When fragrant, add sugar, stock and wine; bring to a simmer. Add cornstarch solution; cook until slightly thickened. Ladle over stuffed vegetables to serve.
