Heat canola oil in skillet, over high heat. Add minced garlic, minced ginger, sliced onions, and crushed red pepper flakes (or broken up dried Chinese hot pepper). Stir-fry 10 seconds. Add broccoli florets and 1/4 cup water. Cover for 3-5 minutes and cook over medium-high heat, just until broccoli is almost done. Add fish sauce (or soy sauce) and 2 pinches sugar. Stir to combine flavors and remove from heat. Serve immediately.

This is also delicious made with broccoli rabe.
