Canned salmon has come a long way in terms of quality, and when combined with chilis, crushed tortilla chips and cumin, moistened with mayonnaise and topped with corn salsa, you almost wouldn't know when it was canned. I've long been a fan of frozen corn, at least when fresh was out of season. As soon as you pick corn, its sugar begins to turn to starch and is not as tasty. (The same goes for peas.) Frozen corn (and peas) is picked when ripe and then immediately blanched and frozen at the height of its tastiness, which is why it is a good idea to keep a stash in the freezer for the off-season. One could argue that you should never eat vegetables out of season, but when you have a son who eats only five vegetables, you can't be all that seasonal.
