I want to know how I can store chopped onions for 2 weeks? I have a cook-out coming up and I need to get ahead of things.
How much onion? It doesn't take much time to chop onion. The only way to store chopped onion for 2 weeks is to freeze. However, once thawed, the texture will not be good. The best answer partly depends on what you are going to use them for. I would say a day in advance is the most you will probably want to do. If they are going to be a raw condiment or part of a salad, you will want them freshly chopped.
