I can't quite figure out how this works:
I caused an AoO and an enemy dragon used a quickened breath weapon (free action) on me as an AoO, while the rule states that an AoO is a single melee attack...
Was that breath legal?

No. As you note, an AoO is a single melee attack; quickened abilities, as they are free actions, can only be used on your turn.
However, GM's world, GM's rules, so I would take it with good humor if it's a home game and not Organized Play of some sort.
No, because a breath weapon is not a melee attack.
Usually, a move action or free action can always be made in place of a standard action, but in case of Attack of Opportunity, that action has to be a melee attack.
