Maybe it's just the latent Midwesterner in me, but my immediate thought was casserole. I bet it would make a delicious broccoli-cheese casserole variation in place of the rice, for example, or tuna noodle casserole in place of the noodles. The nice thing about casserole is that you can add pretty much whatever you have on hand to it and flavor it however you like as long ss all the ingredients go together.
