Look. We know. The folded, pre-fried hard shell is not how tacos are traditionally served in most of Mexico. Fried tacos exist there, of course (tacos dorados are wonderful), but the U-shaped shell from a box is a very American thing.
And yet. Ground beef, shredded iceberg, a snowfall of cheddar, a spoonful of mild salsa, and that crunch. It is a taste of childhood Tuesdays. It is fine. It is, in fact, pretty great.
It shatters on the first bite? So does every good croissant. Stop apologizing for enjoying things.
Final answer: eat the hard shell. Then go get real tacos al pastor tomorrow. You can have both. Nobody is keeping score. (We are keeping score.)
