Each Sunday, we make a list of breakfasts, lunches, and dinners for the week so we can do our first shop at the farmer's market at 10am, followed by shopping at Trader Joe's and Safeway. We then stop at the natural grocer for anything that remains. As a guideline for weekly meal-planning, we've come up with these categories for dinners:
Sunday: Pizza (to use the week's leftovers)
Monday: Pasta (fresh from the farmer's market, can be raviolis or other pastas)
Tuesday: Fish with veggie and grains
We re-arrange these as time and appetite permit. We tend not to plan for the entire week to leave room for leftovers or for the occasional night out. Besides pizzas, we find that good leftover base dishes include risottos, frittatas, and stir-frys. Hope this helps someone out there!
