How would the diet of a medieval king compare to an average persons diet nowadays?

by ActualPimpHagrid

So, how would the average King in the middle ages (we'll say mid-middle ages) in Western Europe have eaten, how much variety of food would they have had? How would the quality of their food compared to something that the average middle class North American have access to nowadays in terms of variety and quality?

The Middle Ages encompasses a period of nearly 1000 years, do you have a more specific place or time in mind?
