As far as environmental impact and waste go, vegetables are obviously a very earth-friendly choice, especially if you are supporting local farmers markets (or growing your own). Since I am living in an apartment with an iffy garbage disposal, composting is not the most convenient option. Using more parts of my veggies means less stinky garbage!
This pasta was adapted from a combo of recipes I've seen on epicurious and thekitchn.com. It's very simple, and follows the formula "Starch + Veggie + Greens + Protein = Full one pot meal" (and this one comes out a beautiful magenta color from the beets!).
