The above suggestions are all good.
I'd say make your freezer your best friend. But not just in terms of ready-to-go meals (e.g. frozen quiche or frozen Paleo lasagna). I buy 3 or 4 pounds of ground chuck and brown it all at once. Then divvy into 1 pound servings and freeze. Since it's already cooked, it's a snap to make things like Paleo sloppy joes, chili, meat sauce, etc.
