Taco sauce tends to accumulate quite fast - enchiladas coming soon. Try Worcestershire sauce on potatoes. Chunk 'em up and boil, drain, hit with a healthy dose of the w-sauce, dried onion, garlic powder, maybe a little parsley or celery flakes for color, coupla hunks of butter for a crispy browning as you toss the spuds around. Experiment with a variety of preserves or jelly. Make your own refrigerator magnets by cutting strips of magnetic tape to fit pics, kid's art, doo-dads or whatever you customarily use that space for.
Wire racks double cabinet space too.
Try Parmesan on green beans, or lemon juice. Delegate the easy, time consuming stuff - makes 'em feel important as a bonus. Never too early to start - you may have a budding star chef who will take care of you in your old age. Didja know you can make tea with cold water - never bitter. Can use hot water from tap or nuke for a minute if time is short.
