I find that I always end up buying more veggies than I need for the recipes I plan throughout the week, so depending on the spread of veggies and whatever proteins I have lying around/are on sale nearby, every so often I completely empty my veggie drawer into a big pot with either a cube of hot pot base or a tin of tomatoes to make enough soup or pasta sauce to last another few meals. Majorly cuts down on my food waste and gets another few days out of my grocery budget.
