Cut up washed broccoli into smaller pieces and add to a bowl.
Sprinkle seasonings with one hand while stirring up the broccoli with the other hand.
Place broccoli on a lined baking sheet (we use a silicone mat)
Roast in a preheated oven at 375 for about 15 – 20 minutes (keep an eye on them, the tops will get a little brown and crispy, and you should be able to poke the stem with a fork)
Sprinkle a bit of mustard powder on the tops!
