Convenience is such a subjective term. Particularly in cooking; some folks are very persnickety about how they prepare dishes, from mise en place all the way through cleanup, attention to detail is key. That can also have a lot to do with the recipe itself, or if the cooking process holds some sentimental value with the individual. Then there are those times when you just want to slap something frozen in the microwave and call it a meal. But by and large, we all learn through experience that you get out what you put into cooking.
