Cut the stems off of the green beans, wash them, and dry them.  Now get out the largest skillet you have that also has a lid. Heat the olive or canola oil in the skillet over medium-high heat. Add the red pepper flakes or Chili Oil and stir to coat the pepper in the oil. As soon as the pepper is stirred in add the green beans and cook, stirring occasionally, until the beans are blistering and browning.  This should take 5 to 7 minutes. Add the garlic and salt and cook, stirring constantly, for about 30 seconds or until the garlic is fragrant and browning.  Add the water and immediately cover. Put the cover on and let the water steam the green beans for 1 to 2 minutes until they are bright green and crisp but tender.  Serve.
