Cut the tops off of your artichokes about 1/3 of the way down. Then clip the spikes off the remaining leaves with kitchen scissors so you don't poke yourself.
Pull the leaves of the artichokes back to loosen them up enough to get the onions and garlic in between the leaves. Mix the onions and garlic together.
When they are as stuffed as you can possibly get them, place them in a steamer pot and cook for about 45-55 minutes, or until the leaves in the middle are easily plucked out. Cool slightly and serve with your favorite, clean dip.
