A German proverb even has the following diet suggestions:"Frühstücke wie ein Kaiser, iss zu Mittag wie ein König und nimm dein Abendmahl wie ein Bettler" ("have breakfast like an emperor, lunch like a king and dinner like a beggar").
Drinks: Tea, Coffee and/or Hot chocolate, at least one sort of juice, in general freshly pressed orange juice, sometimes joghurt drink
Foodies: Quality bread such as farmer's bread ("Bauernbrot") or "Laugenweckle", basically a pretzel roll, spreaded with butter (the one without salt), "soft-cooked", salted breakfast egg eaten in an egg cup ("Eierbecher") while dunking in some small cut buttered bread, different types of cheeses, honey and jams, fresh pieces of fruit or fruit salad, joghurt and granola...
I am always on the hunt for quality foods, especially confitures. When living in Southfields, I was lucky enough to live 5min from a French delicatessen shop called Chanteroy, selling lovely Bonne Maman confitures and French cheeses. I once had a gelée de fruit which tasted like mirabelles, but it was called differently. I browsed the internet but it seems like Bonne Maman stopped producing this sort altogether, I was unable to find it... Anyway, here the shop and address for those interested in checking it out, they also sell their products online if you live further away from the London South West:
