My friend practices macrobiotics and has miso every morning alongside a grain (like amaranth) with veggies (like corn and cauliflower), a green (like blanched kale or watercress) and a sea vegetable (in the miso soup and/or in the form of dulse flakes on the cooked grain). I've tried this several times with great results...feeling grounded, calm, centered, and ready to start my day. It's also very hydrating (the best diet is one where you are hydrated by your food and don't need to down lots of water, which is taxing on the kidneys).
Here's my variation on the morning stew:
Me-So-Happy Miso Soup
1/4 cup yellow onion, diced
1/4 cup carrots, match-stick slices
Several slices of lotus root
1/4 cup daikon, half-moon slices
2 tsp brown rice miso
2-inch piece of wakame, sliced into small pieces
3 cups filtered water
Soak wakame for 10 minutes in some filtered water. Heat onion, carrots, daikon, lotus root and 3 cups of water and bring to a boil. Add wakame and let simmer for 10 minutes. Remove some of the water and mix the miso in it. Add the dissolved miso into the pot. Don't boil once miso is in the pot; it will destroy the digestive enzymes.
Note: Miso soups typically include a sea vegetable for their high mineral content but I have made several soups without them. I just started using wakame, which can be purchased at a natural food store or Whole Foods. Nori is also commonly used.
