If I've understood you properly, you have, or would have, a method
called menu_data in your model subclasses. When it's called it generates
some object-specific data structure or text string and attaches it to
the template_args hash so it is made available as a template variable.
If that's so, I think there's a simpler solution. Delete the last line
of menu_data! Don't attach the data structure to a template variable,
just return the data structure directly. Then change where it's called.
Instead of calling it in additional_data, call it directly as an object
method in the template: [% menu = customer.menu_data %]
