Did you try enumerating the keys of %hash?
foreach my $outerKey(sort keys %hash){
print "$outerKey\n";
foreach my $innerKey(sort keys %{$hash{$outerKey}}){
print "\t$innerKey\n";
}
}

my %hash = (
abcd => {
a1 => 1,
a2 => 2,
a3 => 3
}
);
How can I access the name (abcd) of the passed reference inside of the
subroutine (not just the data a1 a2 etc but the actual key name)?
Currently
what I am doing is passing 'abcd' as a second value to the subroutine,
but there
got to be another way...?
