How many of us could eat an entire bag of Oreos at one sitting? Me, me! How many of us would probably feel sick (and even guilty) about eating that entire bag of Oreos at one sitting? Me, me! And probably everyone else, unless you're Michael Phelps. But how many of us would do it again a couple of months later? Me, me!
Chuck and I learned very early in our marriage that if we wanted to make the bags of Oreos, Goldfish, Cheez-its (or whatever snacky yumminess) last longer than one day, we needed to portion them. As each bag is labeled with a serving size, we take the treats and bag them into little Ziploc snack-sized baggies as soon as we get home from the grocery store. These bags are then put into the pantry, ready for lunches or a quick afternoon snack.
So if we want Oreos, we just grab a little bag of three. If we want pretzels, we just grab a little bag of 30 grams. If we want six snickerdoodles, well, we grab two little bags. (But we know that if the snickerdoodles were not bagged, we'd easily pack away a dozen. Easily. And remember, one erin-sized cookie is approximately two normal-sized cookies, so it's all good.)
This helped us realize exactly how much snacks we were consuming, but also helped make them last. It's amazing how satisfied we can be with 52 Goldfish crackers.
