Trim the ends off the green beans and wash them well. Parboil for 4-5 minutes.
Heat a frying pan over low heat, melt 1 tbsp of butter, and sauté minced garlic for 30 seconds. Squeeze in the juice of one lemon along with a few lemon slices and the remaining butter.
Drain the green beans and plunge them immediately in ice water. This will preserve the colour. Add them to the frying pan with the lemon butter and garlic sauce and season with salt and pepper. Sauté for a few minutes until they are the desired doneness. This will take approximately 5 minutes for beans with a slight bite to them, while cooking longer will produce softer beans. Salt and pepper to taste. Serve immediately.
