Great Cracker Recipe - Looking for a foolproof, really tasty cracker that won't be stale on Day 3. Does such a thing exist?

This is a great recipe: http://smittenkitchen.com/blog/2011/07/flatbreads-with-honey-thyme-and-sea-salt/
I've been making these for years and love, love, love them. I don't make them with the cheese or honey. Most often, I sprinkle za'atar on top with coarse sea salt.

Since I have been making levain breads, I often have surplus starter that used to get thrown away. I have been making a variation of a recipe from KAF, adjusting ingredients and process. Take 1 cup throw-away starter, mix with 1 cup whole wheat flour, 1/4 cup olive oil, tsp or so of salt. Then add flavorings of your choice: I have kneaded in a cup or two of shredded cheddar; various combinations of powdered chipotle and adobo peppers, cumin, whatever. Treat dough like pasta: knead til thoroughly mixed, wrap and let sit for a few hours, then run it through your pasta rollers (I go down to "3" on a Kitchenaid). Put dough on parchment lined sheet pans. Sprinkle with a bit of sea salt. Use a ravioli trimmer to cut into cracker squares. Bake 350 for 18-20 minutes. Addicting.
