For days (okay, it was really hours) a debate raged in the halls of the New Times building over whether or not Popeye is actually a superhero. "No way. He's a cartoon character!" one colleague pronounced."Are you kidding? He's the original superhero!" another cried, just as adamant. In any case, we think it wise for all of us looking to be super-heroic to eat our super-foods, so we'll share our favorite spot to get a dose of spinach. We prefer it fresh, not canned, thank you very much, served in a big woven bowl at Maizie's Café, a sweet little spot just off the light rail on Central Avenue. Piles of fresh spinach are tossed with sherry vinaigrette, dried cranberries, mandarin oranges, toasted almonds, and goat cheese. Enjoy it with a glass of vino; Maizie's has a fine selection of that, too. Popeye might not approve, but we hear red wine's a super-food, too.
