Celestial Salad

This is the salad C is eating at Ocean Beach People's Cafe (Scroll down for photo). My garden is brimming with chard and kale, so it's what's for dinner.

1 bunch kales, sliced thin (I wash the leaves, stack them, roll them if large, and then slice)
1/2 bunch red chard, sliced thin
1 cup black olives, sliced lengthwise
1/2 lemon, unpeeled, chopped
1 small tomato, sliced
1/2 cup tahini
1 teaspoon garlic, minced
4 tablespoons olive oil
2/3 cup water

Place kale in bowl with the sliced olives and a third of the tomato. Place the rest of the ingredients in a blender and blend until completely smooth. You can remove the seeds from the lemon if you do not have apowerful blender. Pour mixture over the greens and mix well.
