Heat the oil in a large nonstick frying pan over low heat. Add the ginger and garlic and cook until tender, about 2 minutes. Add the snow peas and apples to the frying pan and cook, stirring frequently, until the peas are crisp-tender, about 7 minutes. Fold the cooled snow pea and apple combination into a big bowl of slightly chilled cooked rice along with cubes of cooked chicken breast or pork fillet. Toss and serve. This recipe serves 4.
