It depends what the meal is. You can cook simple meals in 20 minutes or less. If you are doing a roast dinner it could take a couple of hours or more in total. The complexity of the recipe and the cooking time add up to make the overall time.
You can make a perfectly healthy stir fry in about 15 minutes.
