Who has good nacho recipes that YOU tried & YOU liked?

I have been making nachos lately out of red, yellow, and orange bell peppers instead of chips. Just slice the peppers into little "boats" and put taco meat, green onions, diced avocado, tomatoes, and cheese (of course) and bake for 30 minutes. Add sour cream, salsa, or whatever you like. These are really, really good.
