Cut up vegetables as soon as you get home from the grocery store. When you want to use them, the prep work is done.

Take the meat you want for dinner out of the freezer and put it in the fridge when you get up in the morning. This way it's defrosted by the time you need it.

Precook foods like rice, pasta, couscous and then refrigerate them in an air tight container. You now have one side dish done for the days ahead.
