Rinse broccoli well. Cut the broccoli florets into bite size pieces. Squeeze lemon juice over the broccoli. Mix it well for 30 seconds or until broccoli absorbs all the lemon juice (leaving no lemon at the bottom). Let the broccoli sit on the counter top for an hour and a half. (TIP: Lemon juice helps remove chemicals/pesticides, improves taste, softens the veggies, removes the bitterness, adds crunchiness, preserves the bright green color and gives delicious lemony aroma.)
