Wild rice and water chestnuts make this delightfully different from the usual hamburger casserole and an excellent choice for a potluck. Our testers loved it!
Cook the wild rice according to the package directions.
Preheat the oven to 350 degrees. In a nonstick skillet, brown the ground beef. Drain off any excess fat. Combine with the rice and all the remaining ingredients in a 9x13-inch baking dish. Bake, uncovered, for about 30 minutes or until heated through.
