For many people lunch is one of the great challenges of healthy eating. The healthy options that are easy enough to bring to school or work just get to be so routine. Fast food and eating out quickly becomes more appealing.

Lunch doesn't have to be just sandwiches, salads and wraps, however. You can get more creative about it.

The first thing to consider is whether or not you will have access to a refrigerator and microwave. Both of these really open up the possibilities. You can keep many foods cold enough with a well insulated lunch box and ice pack, but there aren't good substitutes generally available for reheating food safely.

If you're able to keep your food cold and reheat it, you can bring just about anything you want for lunch. Despite how many people feel about leftovers, they really can be a great option. If you freeze a wide range of them you don't even need to limit yourself to the previous night's dinner, which can help with the boredom factor.

But let's say you're pretty well limited to cold lunches. No facilities to reheat food for one reason or another. What then?

You don't need to limit yourself to your standard foods. You can dress up even basic sandwiches to make them more interesting.

Try using pesto rather than mayonnaise, for example. You'll get a much more interesting flavor out of it.

That's kind of thing is the key. Don't settle for plain flavors. Roast a pepper and add it to your sandwich. Add olives if you like them. Switch up the cheese. Buy better bread.

Salads can be improved similarly. Get something better than a plain head of lettuce. Try romaine, spinach, whatever suits you. Throw in artichoke hearts, kalamata olives, a touch of feta cheese or whatever appeals to you while keeping things fairly healthy.

You can even take some inspiration from those premade lunches kids like. Bring the ingredients to build a quick pizza on a tortilla. You may not be able to melt it all together, but you can roll it up and get a good meal. Don't limit yourself to pepperoni and red sauce. Be creative.

The thing to remember is that you're bored with your lunch because you haven't decided to make it interesting. If you can work with a wider range of ingredients you can make your lunches healthy, simple and interesting. Build the habit and you'll find out that it's really not that hard.
