It's time to think about upgrading your cooking basics.  Let's start with oil. When cooking in a skillet do you reach a basic vegetable oil? The oil you are cooking in adds flavor to the meal, just as the other ingredients do. Olive oil offers a way to infuse different flavors into your food. If you aren't sure, start simple with a basic olive oil. Crisco makes a line of olive oils that are a good introduction. Extra Virgin Olive Oil is the most commonly used variety of olive oil. You can use olive oil in stir-frying, cooking, sautéing, as  a part of salad dressing, or brushed on steak or vegetables for grilling.

Once you've had a taste of olive oil you can branch out to try other varieties. There are literally thousands of different olive oils from all around the world. These oils have different flavors and vendors compete in tasting. Compare that to your average vegetable oil.
