This is an awesome recipe. I found it (or a near-identical version of it) on LindaSue's website a couple of months ago, and have made variations of it weekly since then.

Mexican style, Italian style - with or without bacon - different meats, different cheeses, different veggies, no veggies - it's just amazing how different it can taste and it's awesome every single time. All six of us love it, and I have to make a double batch to ensure leftovers.
