No food waste this week! This is probably the first week since I started my Masters that I can announce that. This is partially due to the fact that I'm eating my house clean over this week and next.
What does that mean pray tell? It means that besides the bare minimums of fresh food (milk, a bag of apples and MAYBE some veggies) I concentrate on eating up what's already in the house. It allows me to get rid of every morsel of leftovers and see the bottom of my fruit and veggies drawer. It's a great way for curbing waste when it gets out of hand.
That said I wouldn't recommend this when you have other people in the house who wouldn't want to eat leftovers 3 days in a row or some really strange recipes to get of that odd ingredient that's been floating around.
Also when working on eating your house clean I would recommend that you do keep a good stock of protein (canned tuna and peanut butter for me), complex carbohydrates (whole wheat bread for me) and plant matter (apples for me). Which a) will not go bad quickly and b) will give you sufficient nutrients should you eat your house clean part way through the week and not have time to shop. (Mostly for nuts like me who work 80% a do a full time masters degree . . . because we like the challenge and as a result have no spare time.)
