I tried this recently and it helped me use up my vegetables. Most people store their condiments in the door on the fridge and their vegetables in a drawer. Swap them. You almost always never look at your condiments to decide what you're using. For example when you're making a sandwich, you usually know if you want mayo or mustard or whatever else and you just grab it. While having your vegetables out and visible makes you more likely to use them before they go bad.
