I am so trying this recipe, it looks delicious! I'm such a crackers&cheese girl, and it's hard to get a good cracker these days when you're low carb dieting. But those pictures look awesome.
As for a low(er) carb alternative to tortilla chips, ever try papadums? They're made with chickpea flour, so they're lower in carbs than corn. Plus you can bake them so they're zero fat. Higher in protein and iron and other good things. I guess the main down side is they don't stay crunchy long once dipped in salsa or queso. They are mad good with quac though. Anyway, just wanted to share that thought.
