Preheat the oven to 400 F and line a baking sheet with parchment paper.
In a large bowl, toss together cooked + shredded chicken breast (1 cup), softened cream cheese (1/2 cup), minced jalapeno (1 deseeded), chives (2 tablespoons), and salt (1/2 teaspoon).
Create 12 flat squares of cheese on the prepared baking sheet, using 1/4 cup of cheese for each square. Be sure to leave 1" between each -- you may need to do this on two baking sheets.
Bake in the preheated oven for 9-12 minutes. You'll know the cheese is done once it starts to brown along the edges.
Allow the cheese to cool slightly until it's cool enough to handle, but before it starts to harden (about 3 minutes).
Scoop the chicken filling onto one edge of the cheese, then roll it toward the open edge.
Serve with toppings suggested above, and enjoy!
Notes
To boil chicken: Place chicken and a generous amount of salt and pepper in a large pot and cover with 1" of water. Bring water to a boil, then reduce heat to medium and let the chicken simmer for 15 minutes. Cut into chicken and make sure it's cooked through. Allow the chicken to rest 10 minutes before shredding.
