Margot Robbie is without a doubt one of the biggest stars of the moment. What does Margot Robbie eat for breakfast? It turns out that she has a very specific avocado toast order. And when she isn’t ordering avocado toast, she is having porridge with blackberries and a smoothie. What I love most about Margot Robbie’s go-to breakfast is that it’s something relatable that I could whip up right now.
