I don’t know why this is such a big deal, as I’ve seen this report several places. I can’t recall ever dipping a tortilla chip into a bowl of ketchup.
I use ketchup in soup beans, on hamburgers, and maybe eggs, although I’m more prone to use salsa on eggs. I use salsa in salads, on tortilla chips, on enchiladas, on burritos, on baked potatoes, etc.
About the only things I use ketchup in is meatloaf, bbq sauce and spread on one slice of cheap white bread in a weiner sandwich (mayo on the other slice of bread).
