Put frozen broccoli into a microwave-safe glass bowl or a big Pyrex measuring cup (2 cup size or larger).
Drizzle on a few tablespoons of cold water, to make the broccoli wet.
Sprinkle salt on top.
Drizzle a few tablespoons of canola and/or olive oil on top.
Microwave for 2-3 minutes per cup of broccoli.
When the broccoli is cooked, there will be some salty water at the bottom. Stir thoroughly, so that this water washes off any patches of salt on the broccoli and distributes the salt evenly across all the broccoli.
