I finally realized that when they listed the zero waste meals, the ecochallenge folks meant not wasting food. That was not my goal at all, since I Never have food waste anyhow. My personal challenge was to cool meals that have no trash from packaging. Today I (nearly) did that, cooking dry beans and rice that were purchased in bulk, plus produce that was all grown locally: lettuce, radishes, and bell peppers. Local veggies are always yummiest and always no trash involved. I did plunge with some cheese and some chocolate added to the meal, which each came in packages. But they were big enough packages that they will be served for multiple meals. I guess I could have skipped those two processed foods and instead just used my homemade yogurt and cocoa powder bought in bulk. Such a challenge!
