Can try one pot dishes. Like cook rice in the rice cooker, together with ingredients, then mix it all up when the rice cooker beeps.
Like for example, throw broccoli, marinated minced meat, mushrooms into the rice before cooking. Add whatever sauces you feel like having (oyster sauce/black pepper sauce/sesame oil etc.etc.) at the end when the rice is done cooking so that you can adjust your seasoning.
Just take note that you need to put less water in the rice cooker pot if you put in veggies that will have water coming out during the cooking process. Like cabbage, broccoli.
