For a long time, almost forever, there has been a widely believed perception that nutritious or 'healthy' food is just bland and boring. It's common sense that a salad is far more healthier than a burger, but our taste buds love the burger way more than the plain salad. However, with the introduction of some kind of seasoning or spices, any food will become exponentially more enjoyable.
But imagine if you were to marinate that chicken breast with flavorful herbs and spices, the taste can change radically, and your boring home dinner becomes a totally different experience.
People will always be eager to point out that, whilst the grilled chicken might include less calories than a large bucket of fried chicken, the taste just doesn't compare.
