If anyone's got tricks for making healthy food that doesn't rely on "cheating" with a bunch of added fats (dairy, animal fats, oils) in order to make them something people actually want to eat, rather than reluctantly tolerating at best, I'd really like to know them. As it is, I try to make a healthy dish in my house—recipe or just winging it, either way—it's guaranteed to be roundly panned (even I usually don't like them much), but I make the exact same thing with liberal use of added fats, and everyone loves it. All the e.g. veggie-heavy dishes we eat that don't elicit a groan either call for lots of fat to begin with (say, cream or coconut milk curry sauces) or are ones I've modified by adding a bunch of e.g. butter. It's even a reliable trick for taking things like soups from "meh" to "wow, that's great!"—generous splash of cream, or butter, or oil. As far as I can tell the full eating-healthy rule should be, "eat food, mostly plants, not too much—and add shitloads of fat to it if you don't want to dread every single meal". I'd love to know other effective "cheats" that don't turn every dish into a calorie-bomb. Though I guess omitting the fat makes the "not too much" part super-easy.
