A quick fix for our lunch is often cold soba or hot udon soup. Hubby always prefer the hot one, and I go for the cold. It's very satisfying to have something quick, healthy and taste good.
I bought some udon like noodle called somen in pink. It's a kind of colouring from a flower. In fact I couldn't taste any difference from the usual white somen. But it's just as good. I boiled my own soup base using Konbu and bonito flakes, then add in low sodium soy sauce for the hot udon soup. As for the cold soup, I add some mirin to the soup and chilled it. Isn't that fast and easy??
