Place roots, carrot, ginger, water and tamari in a shallow pan. Cover and let simmer on low heat until roots are tender (5-7 minutes).
Add shiitakes, cover and simmer for a couple more minutes, then add kale on top. Cover for one more minute and turn off heat so kale becomes tender but not soft.
Serve in a bowl, garnished with sliced scallions, sesame seeds, and kimchi if you like spice.
