In a medium bowl, combine chicken, broccoli (with liquid from package), sun-dried tomatoes with oil from jar, and bread crumbs. Toss to combine.
Arrange mushroom caps, stem side up, on prepared baking sheet. Fill each mushroom cap with chicken mixture. Roast 20 minutes, until filling is golden brown and mushrooms are tender.
