In a container with a lid, combine the oils, garlic and ginger powder, brown sugar, soy sauce and Sriracha. Shake well so that the sugar and powders dissolve. Set aside.
In a bowl, combine the squash, pepper, carrot, broccoli, and cabbage. Toss so that everything combines well. That squash is kindof sticky.
Toss the salad again with the dressing.
Then sprinkle each serving with sesame seeds before serving.
