What we can say with certainty is Taco-Grilled-Cheese Casserole is amazing! Buttered toast sandwiching juicy, zesty, zippy, savory taco beef and bean filling with vibrant salsa and of course melty Mexican cheese? How could anyone say no to that? And no one has to say no to it either, because Taco-Grilled-Cheese Casserole makes plenty for everyone! No need to debate because it’s just that great!
