Humans, like most people, like to eat. They have breakfast, lunch and dinner, as well as a break in the afternoon. Depending on the location, the afternoon meal changes.
Breakfast is usually light, whether in the north or south, though farmers break that rule. Those in the city usually have bread and cheese, some of the richer people having eggs, as well. Farmers have fried meat, bread, eggs and maybe a little milk.
Lunch, for most, is usually a soup, with bread and cheese, or fruit if it is available. Farmers, for lunch, usually have some bread and maybe fruit or cheese, depending on what they have that time of year. During the winter they may have soup, since they have less field work to do.
The mid-afternoon break is usually small, consisting of fruit, cheese or bread, and tea if one lives in the city, or wine if you live in the empire. This is mostly to pass the hottest part of the day in the company of friends.
Dinner is the biggest meal of the day, usually consisting of soup with meat in it or a meat platter of some sort, bread, fruit or vegetables, and possible some cheese. This is about the only time poorer people have meat, and maybe not even then. Ale is a common drink with dinner, wine if the people are richer. Richer people of sweet treats as desert, though even poorer people manage sweet treats on some holidays and special occasions.
