Cut beef and chicken into 1/2-inch cubes and clean shrimp.
Combine 1 tablespoon soy sauce, ginger, 2 tablespoons cornstarch and cold
water; let meat sit in this marinade in the refrigerator for 20 minutes.
In a small bowl, combine the wine, remaining 1 1/2 tablespoons soy sauce,
sugar, vinegar, remaining 1 teaspoon cornstarch, salt, sesame oil and hoisin
sauce; set this seasoning sauce aside.
Heat a large fry pan with oil; fry the red pepper until dark brown. Drain
off the oil. Use same pan and stir-fry chicken first until half done; add beef
and shrimp. Add peanuts. Pour in the seasoning sauce and cook until it thickens.
