Foods that taste good and are "good for you"

Spare me the everything in moderation speech. Yes I know in theory eating a bowl of ice cream could be good for your calcium intake if you offset the rest of it with low calorie foods. That's not what this thread is intended to be about.

So given that, I suppose I should define some basic criteria.

Let's say for the purposes of this discussion foods that are "good for you" are low to medium calorie density, and offer something else beneficial such as protein, calcium, vitamins, etc.

What are some foods that you genuinely enjoy (as much as something as sinful as ice cream or bacon) that would meet this criteria? Doesn't necessarily have to be a single food item. It can be a dish.

I'll start with a couple examples that I like:

Bananas (although I seem to get sick of them quickly)
Chicken Saagwala (sp?)
Beef and turnip stew if it's done right
Some sushi/sashimi (I know some of it is high in caloric content)
Egg drop soup
