I'm in, because we have a ton of traveling ahead between now & EOY, and I need to get through a bunch of stuff & buy less. We don't intentionally overbuy, but we plan our meals as though all four of us will be eating dinner. However, two teen boys regularly have plans of their own (and, they aren't quite organized enough to know that ahead of time), therefore, leftovers often go into the freezer & need to be eaten. We did a solid job this summer when the boys were out of town of pulling out rando leftover meals, & making those.
To answer the macro question of "why do you have so much" from metalcat, my husband's favorite store is Costco. 90% of what we buy there, we use quickly & on a regular basis. However, he prefers to do all of the shopping there, and the 10% of things we use on a more inconsistent basis.... you guessed it, he still buys at Costco. For example, coconut milk & tomato paste. Both are staples, and we will use them up before they expire (and, we paid a discounted price for them), but we tend to grill much more in the summer, and our recipes that use either of those ingredients don't get made until fall/winter.
-Use up 2 cans of coconut milk (make 2 different curries)
-Use up 1 can of tomato paste (use garden tomatoes to make a bolognese sauce)
-Use one frozen container of berries (fruit smoothies for the teen)
I also bought some impulse noodles at Trader Joes that I didn't like (came in a three pack). I either did something wrong, or really need to adapt the recipe. I'd like to use up at least one of those this month as well.
