One of the benefits of preparing a casserole is that you have a complete meal in one single dish, and this means less washing post-dinnertime. Yet another plus is that you can prep the hot dish ahead of time. Then, when you're ready to serve, just put it in the oven and you're all set. My favorite is beef enchilada casserole, which I'm sharing with you below. Enchiladas are riquísimas, but they need to be prepped on the spot; so while some are eating, there's always someone in the kitchen dealing with the next batch. With this enchilada casserole, on the other hand, the entire meal is ready at once, and the whole family can eat at the same time. Best of all, it's ready in approximately one hour. It's also affordable, costing only $3-4 per serving. ¡Buen provecho!
