Carefully remove the core from the cabbage. Place the whole cabbage in a large pot of boiling salted water and cook for 8-10 minutes, or until the leaves are pliable. Remove from water and let cool slightly. Gently separate the leaves.

Place a portion of the meat mixture onto the center of each cabbage leaf. Fold the sides of the leaf inward, then roll up from the bottom to enclose the filling.
In a 9x13 inch baking dish, combine the diced tomatoes, beef broth, and brown sugar. Stir well.

Arrange the stuffed cabbage rolls seam-side down in the baking dish over the sauce.

Let stand for a few minutes before serving.
Notes
These cabbage rolls can be made ahead of time and reheated. For a spicier version, add a pinch of red pepper flakes to the sauce.
