ActionScript 3.0 :: Display Entire Array In Text Box?

How do I display the contents of an array in a text box? (AS3) It's a 2-dimensional array, if that matters.

This shows me the first entry, of course:

ActionScript Code:
outputBox.text = bigChunk[0];

This shows me all data in the array, but of course the user won't be able to see this:

ActionScript Code:
trace(bigChunk);

What I want is this, but of course it doesn't work. Gives me an error because I'm trying to use an array as a string.

ActionScript Code:
outputBox.text = bigChunk;
