These portable and ready-to-prepare macaroni and cheese containers are great for travel as well as a quick and convenient snack. They are designed to be prepared in the microwave, but we have also tried boiling water and pouring it in to prepare the macaroni. This didn't work quite as well, but it was effective enough. We'll use them as a quick snack at home (relatively high in protein, which can help satisfy hunger until the next meal). We'll also use them as a side dish on the road, such as camping (which is when we tried boiling water) or traveling and staying in a hotel. By themselves, they aren't enough for a full meal, but they do make a great side dish. Personally, I wouldn't mind seeing the containers made a little bit bigger. If they were bigger than the current size of about two ounces, then they could serve as more of a main course for a meal (especially a lunch). But right now they are small enough that they need other food on the side. The flavor is pretty good, but I virtually always add some salt and pepper to give a little more flavor (and sometimes a little ketchup).
