Vegetarian Super Slaw--Vanessa

I made this for Mom's birthday and it was a huge hit... original recipe is from Epicurious.

6 tablespoons rice vinegar
3 tablespoons sesame oil
5 tablespoons creamy peanut butter or almond butter
3 tablespoons soy sauce
3 tablespoons (packed) golden brown sugar
2 tablespoons minced peeled fresh ginger
1 1/2 tablespoons minced garlic

5 cups thinly sliced green cabbage
2 cups thinly sliced red cabbage
2 large red or yellow bell peppers, cut into matchstick-size strips
2 medium carrots, peeled, cut into matchstick-size strips
8 large green onions, sliced thinly on the diagonal
1/2 cup chopped fresh cilantro

Whisk first 7 ingredients in small bowl to blend. (Dressing can be made 1 day ahead. Cover and chill. Let stand at room temperature 30 minutes before continuing.)

Combine remaining ingredients in large bowl. Add 1/2 of the dressing and toss to coat. Let sit for a bit before adding remaining dressing gradually -- as the veggies wilt, you may find you need less dressing. Season with salt and pepper and serve.
