1. Gather up all of your Tupperware-style food storage containers. Match the lids. Recycle any that don't match or are chipped, broken or otherwise damaged. Pare down. Most of my clients could cut their collections in half and still have plenty. Consider switching to glass - it's BPA free and doesn't stain.
2. Go through your pantry and toss any expired cans, boxes and jars. Pay close attention to spices, snack foods and cans. I find that these are often expired. Many cans are lined with plastic that contains BPA. If you are going to use canned food, look for ones that say "BPA free" on the label.
3. Grab a paper shopping bag or box and clear off your counter of anything that isn't kitchen or food related or that you haven't used in the past month. Put this bag in the garage for 2 weeks and see if you miss anything. If not, you have permission to recycle it all. If there are important papers on your counters, put those in your office, not the garage. :)
4. Give the refrigerator a quick once over - toss anything that's getting funky or growing more mold than a shot of penicillin. Please recycle the empty jars. Once you've composted any questionable food, give the shelves a quick wipe down with a 50/50 vinegar and water spray.
5. Open your utensil drawers and toss any packets of soy sauce, salt, pepper and the like, as well as any plastic cutlery. Give the gadgets a once over while you're looking in there. Most restaurant kitchens rely on knives, cutting boards, a can opener and skillets to create any number of tasty meal. Chances are, you don't really need 80% of the gadgets in there.
