In a large wok, heat the sesame oil to medium-high.
Add the red onion to the hot pan and sauté 2 minutes, stirring frequently.
Add the cauliflower and continue stirring and sautéing until cauliflower begins to show some color, about 4 minutes.
Add the green beans, red bell pepper, garlic, liquid aminos, and salt and continue to sauté, stirring frequently, until all vegetables are cooked to desired level of doneness. In order to speed up the process, decrease the heat slightly, cover the wok and allow the vegetables to steam for a few minutes.
Serve with desired amount of tahini coconut sauce and cooked wild rice (or brown rice)
