The misconception is tasty food and healthy food are orthogonal qualities; that's thankfully far from the case! For example, you could a make a restaurant quality chicken breast entree with a white wine reduction and heavy cream sauce, seasoned with Herbs de Provence. If you're a follower of Keto, you'd notice these ingredients are all low carbohydrate, and offer protein and fats. Pair with seasoned veggies and you've got yourself an entree, it's delicious, and it's far from consuming the "empty" calories of typical fast food.
