Ok, I'll add in the MSG, inosinates, and guanylates then. Those are natural amino acids that make things taste better, and some of the main things people complain about in "fast" food.
I am kind of a gourmet cook, but I laid out exactly how I get to 20+ ingredients in my home made taco meat. I'm not using a seasoning packet from the store (which, by the way, contains many of the same chemicals, flavorings, and preservatives people complain about in fast food...). I need all of those ingredients, and they happen to be things I always have around.
Are my tacos healthier for you? Probably not. I make my own tortillas too, and I know exactly how much lard goes in those.
