Lay out the flour tortillas on a flat surface. Evenly distribute the chicken mixture in the center of each tortilla (about 1/4 to 1/3 cup per tortilla).
Fold in the sides of the tortilla and then roll it up tightly to form a burrito shape.
Bake:
Place the chimichangas seam-side down on the prepared baking sheet.
Lightly brush the tops of the chimichangas with olive oil or spray them with cooking spray.
Bake for about 20-25 minutes, or until the chimichangas are golden brown and crispy.
Serve:
Serve the chimichangas with salsa and sour cream on the side for dipping. You can also top with guacamole, shredded lettuce, or diced tomatoes.
