Bring a large pot of salted water to a boil. Cook the spaghetti according to the package directions. Drain and rinse with cold water.

While the spaghetti cooks, make the dressing. Combine the Sunbutter, water, honey, vinegar, soy sauce, lime juice, garlic, ginger, and red pepper flakes in a blender or small food processor and process until smooth and fully combined.

In a large bowl, combine the cooked spaghetti, kale, cabbage, carrot, bell pepper, and cilantro. Add the dressing and toss to combine. Serve at room temperature or chilled.

Can be made several hours ahead.
