I'M from Morocco but I live in Luxembourg.
Honestly, I don't have idea what luxembourg's people eat.
Otherwise, I can tell you what my family and I eat for breakfast. So, let's me start, we prepare always Moroccan tea, it is an essential element and must be present on each Moroccan table for breakfast. It is made with water, sugar, green tea and menth.
After, we propose different types of bread, like mlawi, hercha or beghrir.
About me, I love eggs and fruits for breakfast, I think they are healthy and full of protein and vitamins. Take them daily help me to be in good shape.
