Start cooking rice. I also like to steam some green beans or broccoli to go with it.
Put the soy curls into a large bowl, and cover with 1.25 cups water or vegetable broth. Stir so they all get wet. Let sit for 10 minutes.
Meanwhile, blend all the sauce ingredients together in a blender until smooth.
Heat a skillet (a little oil here is optional and does make them more crispy and browned) and pour the soaked soy curls in. Let them cook and get golden brown on the bottom side before stirring. Once golden brown on some parts, pour onto a plate.
In the same hot skillet, heat the sauce and the mushrooms (if using) for about 5-8 minutes, so garlic, onion, and mushrooms can cook and cornstarch thickens it. Add the soy curls back in and stir to coat.
Serve over rice with green onions, sesame seeds, and red pepper flakes on top.
