Wash the meat, pat dry and cut into strips. Peel the onion and chop finely. Drain the pineapple, collecting the juice. Mix the meat with the onions, 3 tablespoons of pineapple juice and 2 tablespoons of soy sauce and let stand covered for about 20 minutes.
In the meantime, cut the pineapple into small pieces, clean and wash the peppers and cut into fine strips. Brown the cashew nuts in a pan (if you have, prepare the dish in a wok) without any fat, then remove.
Heat the oil in the pan, fry the meat vigorously in portions while turning and remove. Sweat the paprika in the frying fat. Deglaze with broth and stew for about 5 minutes. Add the meat, pineapple and nuts. Season everything with soy sauce and Chinese spices to taste.
