Combine the seasonings and add the lean pork strips. Marinate the pork overnight.
Chop the water chestnuts and combine them with the marinated pork. Add the garlic and onion, and mix well.
Lay one sheet of pre-cut bean curd skin on a flat surface. Lightly dab it with water to soften it. Spoon the mixture onto the sheet, fold in the two sides, and roll it up tightly. Seal the edges with the marinade juice.
Heat a wok and pour in 2 cups of cooking oil. Deep-fry the meat rolls over medium heat until golden brown.
Drain on paper towels and serve with sliced cucumber and chili sauce.
