Prepare the Eggplant: Heat a tablespoon of oil in a skillet over medium heat. Add the bite-size eggplant pieces and sauté them until they are tender and slightly golden. Once cooked, transfer the eggplant to a plate and set aside.
Cook the Pork Belly: Using the same skillet, add the sliced pork belly. Cook it until the slices are beautifully browned and crisp. The fat rendered from the pork belly will add an extra layer of flavor to the dish.
Sauce Creation: While the pork belly cooks, mix Ponzu, sugar, sesame oil, Tobanjyan, minced garlic, and grated ginger in a bowl. Stir well to ensure the sugar dissolves completely and all the flavors are well combined.
Combine Pork and Eggplant: After the pork belly is cooked and crispy, return the eggplant to the skillet. This method allows the eggplant to maintain its texture without becoming too soggy from the pork fat.
Add Ponzu Sauce: Pour the Ponzu sauce mixture over the pork and eggplant in the skillet. Stir gently, allowing the ingredients to simmer together for a few minutes. The sauce will thicken slightly, coating the eggplant and pork belly beautifully.
Final Touches: Once the dish is heated through and the sauce is glossy, transfer it to a serving plate. Garnish with sliced green onions for a pop of color and freshness.
