Get a grip. A "bloomin' onion" is NOT meant to be eaten by ONE person. More like 4-6 people.
The same onion, uncooked, would be 40 calories.
4-6? Surely you jest. 2 tops, and then only if they share their fried cheese... ;-)
Have you eaten out lately? The portion for one person at a restaurant these days is what used to be eaten by four to six people. The meals are humongous. And dinner plates have gotten bigger. When Mr. Mew and I go out to eat, if we can't get senior portions, we order one dinner and split it. But we rarely see anyone else doing that.
