Preheat the oven to 400 F. Place the tortillas on a baking sheet and mist them with cooking spray. Bake for 5 minutes, flip and bake an additional 3 to 5 minutes, until crisp.

In a medium bowl, mix together the grapes, jicama, avocado, cilantro, jalapeño, lime zest and juice, and salt.

Spread the beans on the tortillas and top them evenly with the salsa mixture.
