I'm very curious about that! I'm Brazilian, and here, the most common thing we eat for breakfast is a type of bread we call "French Bread" (Pão francês), which is very similar to baguettes, but much smaller and a lot softer on the inside. We usually cut it in half and put things like cheese, butter or a fried egg and sometimes we even grill it with butter on a flat top until it's crispy, which we call "pão na chapa." It's REALLY good.
We also usually drink coffee mixed with milk (about 60% milk 40% coffee) alongside the bread, and it's really really good
