I have made all of those things, wraps and quesadillas and the like, but the most fun thing I ever made with these is a Torta Rustica, an Italian type cheese and vegetable pie in many layers.

I used the tortillas on the bottom, sides, top and between layers, in a large springform pan. The layers were made of ricotta, parmesan, spinach and eggs. Garlic, nutmeg, fresh ground black pepper were the main seasonings.

Delicious and fun, and very suitable for a special family potluck. Everybody loved it, including me. Made 12 HEARTY servings. Used 4-5 tortillas total (can't remember how many layers I ended up with.

PS: these tortillas are available in Canada, check out the LowCarb Co-op forum, 1 package is very expensive but the discounts make them very do-able if more are bought at one time, which also spreads out in-Canada shipping costs... and the price hasn't changed despite the dollar fluctuations (ahem, DROPS) since last September.
