You can make a ton of sweet glazed carrots in a rice cooker. All you need for seasoning is instant bouillon granules. Freeze them for an easy and quick addition to your bento.
I wanted something quick and easy to go in my bento every day. I make a lot at once and freeze. This gives me a good nutritious balance.
The carrots will soften after about 25 minutes. If you cook them any longer or keep them warm in the cooker, they might fall apart. Adjust the cooking time to suit your rice cooker.
