One of the best baked fish stick style recipes I've tried. Usually the breading is only crisp if it's fried. Not here, nice crunch and it was a great idea to use sour cream to help adhere the coating to the fish. Much better than the typical gloppy egg and bread crumbs and easier to work with. Instead of corn chips I toasted some corn tortillas in the oven and then crushed them with a rolling pin. Served with with quick and easy avocado and tomato relish (see links).
