Preheat oven to 400 degrees. Unfold thawed puff pastry and roll out so it's about an inch bigger on all sides. Cut each into four equal rectangles.
In a large, non-stick skillet, heat the oils to medium heat. Add carrots and cook for 5-6 minutes until beginning to soften. Add the rest of the vegetables and cook, stirring occasionally for another 5 or so minutes. Add the shredded chicken, sauces, and garlic powder. Stir well to combine and remove from heat.
Evenly distribute filling among the 8 pieces of puff pastry (about 1/2 cup). Fold 2 sides inward, and then roll up like a burrito.
Place rolls, seam side down, on a baking sheet. Bake for 20-25 minutes, or until puffed and golden brown.
