Place the broccoli heads into a steamer basket or other steaming appliance. Add the lemon zest over the top broccoli.
Squeeze the juice from 2 lemons into the water that's being used to steam the broccoli.
Steam broccoli for 3-5 minutes, or until turns bright green. Remove from heat immediately to prevent over-steaming.
Season with salt and pepper to taste.
Serve Lemon Steamed Broccoli as side dish.
