Add eggplant and pepper to the meat. Season with rice vinegar and pour in 3 tablespoons of broth. Stir well and simmer for about 5 minutes. The meat is ready!
By this time, the rice is cooked, take out the bags, let the water drain and put it on a dish.
Serve the meat hot with warm rice. I served the rice sauce in a bowl with soy sauce mixed with rice vinegar to taste. You can sprinkle the dish with finely chopped green onions.
