This is so easy. Heat a dry skillet for several minutes over medium heat. Add a bag of frozen broccoli florets to the hot skillet (no oil). This cooks quickly, so don't leave it. Stir the broccoli frequently to prevent burning. You want some browned places on the broccoli. Cook for 7-8 minutes, or until the broccoli is cooked to the tenderness you like. Add a couple splashes of Bragg's or soy sauce and let it cook down. Remove the broccoli from the pan to a serving bowl and drizzle a little hot chili oil over it Optional, of course). Cover this with some foil to keep it warm while everything else is cooking.
This method works for brussels sprouts and green beans as well. You can add mushrooms to the mix too.
