Spiralize the zucchini and yellow squash. Set aside in a serving bowl. (If you do not own a spiralizing tool, you can make noodles with a standard peeler or julienne peeler).
Place all of the remaining ingredients except for the cilantro in a blender and process until smooth.
Pour the sauce and 3 tbsp cilantro over the noodles, and stir until combined.
Top with tomato, bell pepper and remaining cilantro.
