If you try to plan advance monthly or bi-weekly menus it can be difficult to balance variety with the staples that everyone enjoys. Parenting weblog Simple Mum recommends establishing a theme for each day of the week such as pizza day or crock pot meals day. That way you know what type of meal you need for all of your open slots and your family knows what to expect at most meals.
If you're having a weekly pizza day this also makes it easy to stock up on bulk pizza ingredients. The author at Simple Mum tends to use the same theme days for a season and then switch things up. At the time of her post in April 2009 this was her current selection:
Mondays - pasta Tuesdays - soup, salad, and/or sandwiches Wednesdays - stir fry Thursdays - crock pot Fridays - pizza Saturdays - something new Sundays - something easy
You can see in the source link below how this weekly theme is expanded to simplify making a month's menu plan.
If you're trying to get ahead with meal preparation consider using this technique to save money buy buying in bulk and saving time by efficient planning. You can include ethnic cuisine categories, preparation styles, or any other criteria that will result in a better meal selection.
