In a large skillet over medium heat melt the butter, add garlic and a pinch of red pepper flakes. If you like it spicy, add a large pinch of the red pepper flakes. When the garlic starts to sizzle add the green beans, season with salt and a small pinch of sugar. Cook about 2 minutes. Add ¼ cup of water, cover and let cook for 5 minutes. Uncover and turn the heat up to high. When the water evaporates, season with salt and pepper and serve immediately.
