Heat oven to 350
Place chicken in a large pot and cover with water. Bring to a boil.
Reduce heat and simmer gently, covered, for 10 minutes.
Allow to cool and cut into 1/2-inch pieces.
Coat a 13 x 9 x 2-inch baking dish with nonstick cooking spray.
Add burritos, cutting to fit in a tight single layer (you will need 10 to 12 burritos, depending on the brand).
Scatter the chicken over the top.
In a medium-size bowl, mix together milk, soup, 1 cup of the cheese and the olives.
Pour mixture evenly over the chicken and burritos.
Top with remaining 1/2 cup cheese.
Bake at 350 degrees for 30 minutes or until heated through and bubbly.
Cool slightly before serving; sprinkle with cilantro leaves, if desired.
