Heat up some olive oil in a sauté pan. No measuring here, but maybe 2 tablespoons. Cut an onion in half and then make thin slices. Throw the onions in the pan and give them a stir so they all get coated with the oil. Cook on medium, stirring semi-frequently.
In the meantime, steam about a pound of green beans. When the green beans are steamed to your liking, throw them in with the onions. At this point your are going to add some garlic; sliced, chopped, minced. I used a garlic press and two cloves of garlic. Maybe add a little more olive oil if you think you need it. Give everything a good stir.
Turn the heat up to medium-high and season with salt and pepper. The finishing touch; freshly grated nutmeg (ground in a jar works just fine). But, this gives you an excuse to use one of these super-cute mini graters.
