I'm flying solo this weekend and I think I may make a batch of sour cream enchiladas from Pioneer Woman with half the sour cream swapped out for Greek yogurt.
One of my favorite bloggers, Brooke from Inchmark, posted a great weekly meal planning template on one of my other favorite blogs, DesignMom. You can download the template there.
I think I follow my mom's method of listing out food by where it is in the store. I start with produce, then have meat and dried goods in the middle of the list, and end with dairy items. But I don't end up having room for the actual meals I've planned, so I write those on the back.
