2 full heads broccoli (stems too, not just the crown)
1/2–1 tsp salt
1/4–1/2 tsp pepper
In a cast iron skillet or heavy-bottom pan, heat olive oil over medium-low heat for 2-3 minutes.
Meanwhile, prepare the broccoli by cutting entire head of broccoli in half. Laying the flat side down, cut off each floret from the base of the floret all the way down to the bottom of the stem.
When the oil is hot, add all the broccoli to the pan, arranging so that as many pieces as possible are touching the bottom of the pan. Season with 1/2 tsp salt plus pepper to taste and allow to cook for 5 minutes, undisturbed.
After 5 minutes, stir and rearrange the broccoli so that the sides that were down are now facing up. Season again with salt and pepper and cover with a lid. Allow to cook for 3 more minutes.
