I think most of us know that, after eating, the bulk of our energy goes toward digestion, thus making us feel a little sleepy. After dinner in my house is a time for finishing homework and spending time with my husband, so the last thing I need to be doing is spending an hour in the kitchen recovering from dinner. Therefore, I practice "Clean as You Go". (Starting with a clean kitchen is a big help!)
First, if I create any sort of trash or recycling while cooking, I take care of it right away. For example, I rinse cans, remove labels, and get those cans to the recycler container in my pantry. If I'm done with an ingredient, I put it right away. If I'm using a leftover from the fridge and I've emptied the container, I rinse all food residue away or allow it to soak while I continue meal prep. Cutting carrots? I have a white plastic cutting board, so for any food that stains, I make sure to scrub it a bit with dish soap and set to the side until I load the dishwasher. And, of course, wipe up spills immediately so they do not become hardened.
Remember, life doesn't always go as you plan, and there are times when the kitchen will just have to wait. In those instances, at a minimum, make sure all leftovers are put away and that plates and utensils get a quick rinse so they won't have to be soaked later. Enjoy dinner and enjoy life!
