What I used to refer to as "my parsley problem" was the fact that I wasted so much of it. It's a staple in our house, I use it for a few of our favorite meals, and so I'd buy it at the market almost every week. And every week, I'd toss out at least half of it, or the whole thing if we hadn't had clams linguini or salmon patties. It usually lasted a couple of weeks, but it was never used up. I know some people have this same problem with cilantro or other fresh herbs. You want to have it on hand, but at the same time you never use the entire bunch.
This was the easy solution. I bought a parsley plant for about a dollar, planted it with whatever potting soil I had, and made sure I watered it a couple of times a week. Now every time we have clams linguini, I just go outside and clip off what we need. No waste, ever.
It's a small thing, but you know my philosophy: baby steps. It's easy to change a habit by incremental degrees.
Maybe I should be posting this the next time we have zero food waste, but I felt like mixing things up a bit! Do you have any examples of a problem you'd accepted for years, that you were able to change with one small action? Something that saved energy or food or time or money?
