It's so easy to cook green beans to look like a professional dish. Trim the stem ends off then wash and thoroughly dry. Heat a cast iron skillet on medium-high with good cooking oil, then toss in the green beans. After about three minutes, use tongs to flip the beans over; they should be blackened on one side. Keep moving them around the pan until they are evenly blackened, then arrange them on a platter. Keep the skillet on the heat and add in your sliced garlic, capers and red pepper flakes. Once these are nicely sautéed (about one minute) pour them overtop the green beans and season with coarse sea salt and some fresh lemon juice.
