In a medium skillet with a lid, heat the olive oil over medium high heat, then add the garlic (1 teaspoon for a milder garlicky flavor, 2 teaspoons for a full-on garlicky flavor) and swish it around for about 30 seconds until you can smell it.  Add the broccoli and stir and toss to coat with the oil.  Season with salt and pepper, add 1/4 cup of water, cover the pan, and steam until the water is evaporated and the broccoli is tender.  Sprinkle with the red pepper flakes if desired. Serve hot.
