Tastes a lot like Chef Boyardee canned mearty pasta. Only much better, and entirely vegetarian (if you can find veggie mushroom gravy mix; Kroger carries it in Mississippi) with a vegan option that I didn't like quite as much as the cheesy version but was still pretty tasty. I came up with it in an effort to make pasta while lacking the technology to boil a pot of water but having an oven handy. I've been making it for almost two years and it has turned out awesomely tasty every time. There are many variations to match what you have on hand but if you want a large batch of handy, healthy brown-bag lunches-what I always make it for-it's worth a special shopping trip. And you don't have to pre-boil the pasta. At all. And it keeps tastily for at least a week in the fridge.
