Saucy Asian Bok Choy - cooking recipe

Ingredients

1/2 teaspoon ground ginger
1/2 - 1 teaspoon fresh ginger, grated (a full teaspoon will make it pretty hot)
3/4 teaspoon tamari
1 tablespoon no-added-salt tomato paste
1/2 teaspoon vegetable oil
1 large garlic clove, chopped
1/3 cup vegetable broth
4 cups bok choy, chopped (including the white parts, chop them finely)

Preparation

Combine all 7 first ingredients, for the sauce, in a small pot and bring to a simmer.
Add white parts of the bok choy and cook on medium-low, covered, about 5 minutes, till softened.
Add the green parts of bok choy and let cook 3-5 minutes more. Stir, remove from the heat, cover and let the greens soften further for 3-5 minutes.
Dish it up and spoon some of the sauce over each serving. This is also quite good as leftovers served cold.
