Here’s a fun, budget-friendly project that also fights food waste: regrowing veggies from scraps! Scallions, celery, even lettuce. It’s amazing what a sunny windowsill and a little water can do. Not only will you save money on groceries, but you'll also get a sense of accomplishment every time a new green shoot pops up. It's like having a kitchen garden without needing, well, a garden.
