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.
6 cups or a pound and a half of cheese, shredded, half cup of flour, half cup of butter, 2.5 cups of half and half, 1.5 cups of milk. Add a teaspoon of sodium citrate to that much cheese sauce, or about 8 cups of sauce. That will make enough sauce for a pound of macaroni product noodles. I generally do twisty or shells
If you don't have pure sodium citrate, a single slice of American Cheese will do the trick.
