One pot meal or one dish meal are simple meals cooked with little fuss and minimal clean-up. And almost always contain meat and vegetable in one dish.
Some people like to put in every items of the dish, such as rice or noodles in the same pot, making it truly a one pot meal. Personally, I like to serve the rice, noodles or bread separately.
While such all-in-one cooking keep things simple, not all one-pot dishes are easy to prepare.

I served this stew with toasted baguette and steamed fluffy mantou. The beef in this stew are soft and almost melt in the mouth, because of hours of stewing on the stovetop. The gravy is full of flavor and best for dunking baguette and mantou. So which pairing is better? I like both.
