So, I decided to consult with Mollie and Pam:
I selected 20 weeknight dinners for the month. Weekends can be more spontaneous. Meredith has agreed to eat some seafood, so there are one or two meals with shrimp or clams. The rest are either vegetarian, or can be prepared with the meat added at the last minute, so I can serve hers plain and double-up for Haley.
I made my calendar and a shopping list for each week. So far, so good. We've had a few unusual things and we've liked everything so far. The best part is having a plan, knowing what I'm going to make, and having the ingredients at-the-ready. What are you making this month?
