I designed the plan to have simple, quick meals on weeknights and any longer meals, or ones to be made in larger batches, are on weekends. I generally try to keep weeknight meals to 30 minutes cooking time, and weekends might be 45 minutes or an hour. I also try to keep meals to one or two pots so that dish cleaning time is minimized as well.
If you have days when you just have absolutely no time to make a meal, I have a section in the site where I divulged my secret shortcuts and options for making packaged foods healthier, as well as tips for eating out and at parties.
