It's been a long day, the last thing you want to do is go to the store on your way home from work, the only problem is you and your family have to eat something. Resist the urge, don't stop and get takeout. Just keep my favorite pantry essentials stocked in your kitchen and you will be able to whip up a meal in no time with just a few ingredients.
The key to keeping yourself on track and eating healthy is to have the food in your house available whenever you need it. Most of the items that I keep stocked are either non-perishable or can last in your fridge/freezer for a couple of weeks. These items obviously are just a few of my favorite, but you can tweak them to your family's liking.
