You can purchase either a head of broccoli, broccoli crowns, or a bag of broccoli florets for our broccoli salad recipe. You'll just need the broccoli crowns or the "tree" part of broccoli florets if you have those. Cut the broccoli stems from the stalks and just use bite-size pieces of broccoli florets for the recipe. Broccoli stalks are totally edible and can be used for other purposes.
