We waste a lot of money on food each year. Something like, 165 billion dollars worth.

    No one likes to waste food, but we’re probably all guilty of it. In the spirit of frugality, I thought I’d round up a few ways to cut back on food waste and make the most of your groceries.

    Keep Track of Perishables With Your Receipt

    I wrote about this over at Lifehacker, and I incorporated it into my own grocery routine. Check out this short video to see how easy this tip is:

    Find the True Expiration Dates of Food

    Harvard conducted a study a couple of years back that found most of the expiration dates on food are total baloney (yes, baloney–all this food talk is making me hungry). They’re based more on marketing and less on health standards. So, if you’re going by the label, you may be tossing out perfectly good food.

    For better food expiration dates, check out EatbyDate.com, StillTasty.com, or the USDA’s FoodKeeper app.

    Each of these are databases that give more accurate expiration dates for a number of foods. You can learn when food actually spoils, based on how you store it. You’ll even get tips for prolonging its shelf life, and FoodKeeper will send you reminders for stuff you have at home. All solid options.

    Use a Backup Grocery List

    Meal planning is essential for staying within your budget, and the apex of a meal plan is the grocery list. It keeps you from mindlessly buying a bunch of stuff you don’t need, only to throw it out later. But we all get busy. The week gets away from us. There are days when grocery planning sounds like the most dreadful of chores.

    For those days, have a backup grocery list ready. This is your go-to, tried-and-true list of stuff to buy at the grocery store. This list should include enough food items to make your weekly meals–no less and no more. And those meals should be easy, too. Your list might only include noodles, ground beef and tomato sauce for making a week’s worth of pasta. That’s fine–it doesn’t have to be exciting. It’s simply a default list for those weeks you don’t feel like planning.

    Try the Inverted Pyramid Method

    On those weeks that you do have time to meal plan, here’s the easiest method I’ve come across for getting it done. Start with your biggest meal of the week, and work your way down. Use any leftover ingredients you’ll likely have from that meal to plan the next meal. Then use any potential leftovers from that meal to plan your third meal–and so on, until you’ve got a week’s worth of meals.

    Cut back on food waste

    Above is a (poorly designed) example of this method, showing you how the ingredients overlap.

    “Iron Chef” Your Meals

    This method is a crowd favorite. It’s resourceful, and it’s creative–what’s not to love about it?

    Here’s how it works: you try to make a meal out of only the leftover ingredients you have on hand at home. It’s sort of like the show Iron Chef in that you’re limited by the need to use those ingredients. It sounds silly, but this method is responsible for some of the tastiest dishes I’ve made–chicken lettuce wraps and gnocchi to name a couple.

    But what if you’re not feeling very creative? Not to worry; that’s where Supercook comes in. Head to the site, enter the ingredients you actually have on hand, and Supercook will pull up a list of recipes that you can make.

    These are just a few methods I use to optimize my groceries and avoid waste. I might not put a dent in that $165 billion. But by planning, keeping track of what I have, and making the most of leftovers, I’m able to keep my own grocery costs down.
