Pick up some onions, peel, chop and saute on the stove in a bit of butter or olive oil. There is nothing better than the aroma of onions simmering. Think of all the great things that simply start with onions. Onion soup or onions added to a roast chicken or beef. You can add herbs to flavor.
Yesterday, I made a post roast and the base was sauteed onions and freshly grated ginger. You can add other veggies after you have created the sauce. Onions are easy to store and can keep for a few weeks in a dark dry spot. Onions add so much flavor to soups and sauces.
