Made this with 8 oz of lean ground beef, a diced zucchini, a head of broccoli, and no mushrooms (husband won't eat them). Used a jared pasta sauce instead of the canned tomatoes, and added 1/2 tsp of Italian spice and about 1/4 cup of red wine to the mix. Cut back on the ricotta a bit and threw in small amount of mozzarella and parm, and then broiled it for about 4 minutes to melt/warm it all. Otherwise, followed the recipe. Was very tasty.
