After reading about jackfruit I had to give it a try and this is what I came up with.  There is more information on the recipes for the different layers just follow the links.  If you opted not to use tortillas I think the elements would be good on a hoagie similar to a Vietnamese sandwich.

8 tortillas (we used medium sized flour. If you use smaller tortillas you may need more.)
Fresh Spinach
1 batch of Bool Kogi Inspired Jackfruit
1 batch Asian Style Broccoli Slaw
1 batch Cucumber Salsa
1 jalapeno seeded and cut into thin strips

We layered ours in the order above (yes, we put the spinach on the bottom) but have fun. We also added some of the liquid from the Slaw over the top.
