High quality (which is very hard to find these days in my experience, at least outside of Indiana/Illinois) old-fashioned Cantonese-American food.
It has to be high quality, though! No canned mushrooms, no “chicken-like” prefab protein, no deep-fried sludge (including factory-issue egg rolls). Has to be cooked to order from fresh ingredients, including homemade sweet-and-sour sauce.
But if it were all those things, I could happily eat it every day, forever.
In the original question if we replace “meal” with “cuisine” then I agree that this would come the closest to satisfy, but still would get boring after a while.
