preheat oven to 425 degrees and line a baking sheet with parchment paper.
wash and chop broccoli into 1-2 inch pieces, both the head and the stem
now either lay the broccoli on the sheet pan and drizzle the olive oil over it OR put in a bowl and drizzle the olive oil on top
toss the food in the olive oil so it's well covered
sprinkle with kosher salt (or any other seasoning you want to use)
spread out on parchment paper lined baking sheet and put into the oven at 425 degrees for about 30 minutes
