As Russ noted some time ago, you never want to be the guy who heats up a fish dish in the microwave at work. No matter how tasty it might be, it puts a weird smell in the air. Always. Your co-workers will hate you. I learned that the hard way.
But have you ever noticed that the exact opposite happens when you heat up Italian? Suddenly, you become uber-popular and everyone's interested in what you're eating. And it doesn't have to be something from a fancy restaurant or homemade. I mean you could nuke a bowl of Chef Boyardee, and if it weren't for people recognizing the classic shape of spaghetti-o's, you could probably get the whole lunch room fascinated with your meal. Sprinkle some parmesan cheese on top, and your associates might start asking you to cater their weddings and bar mitzvahs. Sterile office environments and the mundanity of the workaday world somehow enhance people's interest in food. Fragrances seem so much stronger when smelled from a cubicle.
And on this serendipitous encounter, the bechamel is part of a similarly-packaged lasagna-esque dish just like last time, but now it's got better taste. I mean, I can't quite distinguish the bechamel from the pasta, ricotta, spinach, and tomato sauce. So I still couldn't tell you what it tastes like. But now I won't associate the word "bechamel" with nastiness.
The flavors that I could taste were very well balanced, and I never found myself wishing the cannelloni had any kind of meat or meat sauce, as I often do with vegetarian Italian. There was plenty of pasta and ricotta. If anything was slightly lacking, it was the spinach. The dish required an extra minute of heating, bringing the total time in the microwave up to eight minutes. That's not unreasonable, considering what you're getting.
I'm sure it would have turned out differently with a more traditional heating method, but the product was fairly soupy when it emerged from my electromagnetic particle disruptor oven. All of the sauces and cheeses created a wet conglomeration in the bottom of the microwave-safe heating carton. It was messy but tasty, easy, cheap ($2.49), and fast. Oh—and it smells really good, too. Heating it up at work just might make you the most popular guy in the lunch room. Sonia sat this one out, so I'll score it on her behalf. I'm torn between a 3.5 and a 4, so I'll give it one of each.
Bottom line: 7.5 out of 10.
