I heard someone say this in a video recipe, followed by way more cheese than you should eat at once. It occurred to me that the phrase means ample, not nutritious.
Nah cheese is really good for you it is usually easier to digest than milk. It has some pretty important fats and all 9 essential amino acids. It is calorie dense which makes it a great pick me up snack. And if you're a vegetarian cheese is one of the few foods that fill the role of meat.
