What saves YOUR sanity when menu planning?

Go check it out. Pretty cool idea! =) Makes it easy, for sure!

I try to do something similar. Being Vegetarian, sometimes it's hard to find variety. When I'm planning my menu each week, I aim to pick out an Italian, Mexican, and Indian meal. That covers at least 3 nights. Then I usually go for either some sort of salad or sandwich, and also one casserole.

When you think about your menu in this way, I think it makes menu-planning much easier!
