Tear the leaves off the kale into bite-size pieces. Slice the stems into 1 inch long pieces. Blanch the stems for 2 to 3 minutes. Remove, place in a strainer, quickly rinse under cold water to halt cooking. Blanch the kale leaves for 1 to 2 minutes, and rinse in a strainer under cold water. Drain.
Heat the oil in a medium skillet and sauté the garlic for 1 minute. Saute the onions for 2 to 3 minutes. Add the kale leaves, stems and shoyu soy sauce. Sauté for 2 to 3 minutes, stirring constantly. Sprinkle the lemon juice over and toss to mix. Serve immediately after adding the lemon juice or the leaves may loose their bright green color.
