Does it need to be in stash? How about a method in MyApp.pm that 
supplies the data? Eg.

sub menu_data {
     my $self = shift; # same as $c
     return {
         item1 => 'some data',
     };
}

Or just use some Moose goodness instead:

has "menu_data" => (
     is => "ro",
     isa => "HashRef",
     default => sub { shift->config->{menu_data} }, #pull data 
from config
);

And then later in your template:

[% c.menu_data.item_1 %]


If you really do want the data in the stash, then create the 
object at app startup and then assign it to stash on each request:

after 'prepare_action' => sub {
     my $c = shift;
     $c->stash( menu_data => $c->menu_data_object );
}
