Heat oven to 350°F. Line a baking sheet with parchment paper.
Sauté the onions and bell peppers with the tablespoon of oil over medium heat for a few minutes, until they have softened a bit.
In medium bowl, add cream cheese, chicken, onions, bell peppers, salt, pepper, and milk; mix well.
Separate the 2 tubes of dough into 8 rectangles total. If your dough is perforated, pinch the seams together as needed to seal them. Lay out the dough on the parchment paper. Equally distribute the chicken mixture between the 8 pieces of dough. Pull 4 corners of dough to center of chicken mixture; twist firmly. Pinch edges to seal.
Brush tops of sandwiches with 2 tablespoon melted butter; sprinkle with crushed croutons.
