One of my favorite Italian dishes is stuffed shells. They are pretty easy to make, but take time.
So, last week, the Mrs. was at the prepared food section of the grocery store, and picked up shells already made up, in a nice tomato sauce. Not only were they pretty good, but the price was very reasonable. She paid $6 for 8 of them. The local pizza shop sells a dinner with 4 shells, and some bread for over $9.
So, it was a little bit cheaper, and much more convenient. Mrs. heated it up on the stove, so she didn't even need to turn on the oven.
This can be a better alternative to picking up dinner from a restaurant. It's not quite as good as home made, but sometimes, one has to take a shortcut.
