I made three batches of this at once, using approximately 2 1/2 times all the ingredient amounts; one batch for us and one batch each for two of my friends who recently had babies. Personally, I felt like it did not have enough sauce on it, but that could be beacuse I messed up on the amounts (I am really bad at this and famous for asking Chuck things such as "what is one-and-one-third times three-quarters of a cup?"). Regardless, next time I will try to add some salsa to the ground beef mixture.
As with most casseroles, individual servings do not photograph well so here is the final dish!
Since that was the only adjustment I would make, I will just link you directly to the original recipe at Taste and Tell:
