*measurements are sliding on oil, salt and pepper because you really want to eyeball this for flavor. I usually wing it and keep in mind that everything is a light seasoning. Remember - you can always add seasoning but you can't take it out. The amount of salt and pepper really depends on how much broccoli is on your sheet pan.
*Making more than one tray of broccoli? I rotate the top sheet and the bottom sheet during cooking.
*Want to jazz it up? When broccoli is cooked, you can hit it with a squeeze of fresh lemon juice. You could also add a little bit of grated parmesan or sprinkle toasted pine nuts on top. Chef's choice.
