For an extra layer of flavor, try adding a pinch of red pepper flakes to the green beans while they are cooking. To toast the pecans, spread them on a baking sheet and bake at 350°F (175°C) for 5-7 minutes, or until they are fragrant and golden brown. Alternatively, you can toast them in a dry skillet over medium heat, stirring frequently, until they are fragrant and golden brown.
