I always plan our meals weekly, though I often switch nights around. I love knowing that I have a plan for the week and all the ingredients on hand. In general, we try to eat fish once a week and often have one vegetarian meal per week. I don't usually plan side dishes and vegetables - it depends on how busy the day is. We eat brown rice quite a bit, but it takes about an hour to make. I do freeze family-sized portions, which works really well. We also eat a lot of salad, broccoli, grilled vegetables (in the summer especially), veggies and dip, and sugar snap peas.

We have a very busy weekend next weekend, so I'm holding off on planning for now.
