Preheat oven to 400 degrees F. Lightly spray 2 24-count mini muffin pans with nonstick cooking spray. Set aside.
Unfold thawed pastries onto a lightly floured surface. Cut each pastry sheet into 36 squares for a total of 72 squares (I use my pizza cutter).
Add two dough squares perpendicular to each other to 36 muffin cups as illustrated in above photo. (Note, they will fill only half of the second muffin pan).
Top each dough cup with 1 tablespoon Beef Brisket followed by 2 teaspoons cheese and optional jalapeno slice.
Bake at 400 for 12-15 minutes, or until cheese is golden. Wait 5 minutes then remove to a baking rack to cool slightly before eating. Enjoy!
