I love German food and I love German idioms. Here are three great ones on the topics of three diet and language staples: sausage, butter, and chocolate.
Es ist mir Wurst
Literal meaning- It is sausage to me.
Figurative meaning- It doesn’t matter to me. I don’t care. Whatevz.
Alles in Butter!
Literal meaning- Everything in butter!
Figurative meaning- It’s all good! I got this!
Literal meaning- chocolate side
Figurative meaning- your “good side”, like of your body or your personality
