Bread

Bread was a staple food in many cultures in known space. It was often prepared by baking a dough of flour and water. Salt, fat and yeast were common ingredients, though breads may contain milk, eggs, sugar, fruits, vegetables, or nuts.

Bread was an available food to the many pilgirms who traveled to see the Emissary's land after 2375. (SS New Worlds, New Civilizations (A Walk in the Path))
