On a cutting board, slice the eggplants into halves lengthwise and cut them into thick slices, about ¼ inch thick, and leave about ½ inch intact. This creates a cavity in each piece, resembling a box or pouch.
Combine the ground pork, seasonings, and sauce in a large bowl. Mix well to combine.
Fill the eggplant slices with the prepared filling mixture. Tap a spoonful of the ground pork mixture into each eggplant slice's cavity, pressing it in gently. The final result looks like eggplant burgers! Repeat until all the pieces are filled.
Heat a generous amount of cooking oil in a deep pan or wok over medium-high heat. Meantime, dip both sides of the stuffed eggplant into the batter. While deep frying is a popular method. You can also use an air fryer if you are concerned about too much oil or have some dietary restrictions.
Carefully place the stuffed eggplants into the hot oil and fry until golden brown and cooked through—a few at a time and turn them occasionally for even cooking about 3 minutes. Remove and drain excess fat on a paper towel.
Serve hot as an appetizer or side dish. You can enjoy them as is or serve them with a dipping sauce, such as chili sauce. Some people also like to serve it with a savory sauce poured over the top. This delicious sauce may include soy sauce, oyster sauce, or various seasonings.
