Pain grillé IS toast, correct? In other words, it is bread that is heated Brown, or grilled or however they want to say it, in the end we call it toast. There is no need to specify toasted bread. Now, if it was another type, you would say toasted Bagel, or toasted croissant, or toasted hamburger bun. But, without the specification, in American English, bread is the default. Therefore, I think my answer of toast instead of toasted bread should be accepted.
Thank you, I was curious about the lack of a conjunction here. Wow, sometimes I have to say French is a bit strange, they do seem to throw in a lot of little words à, de, au, dans, a lot, here, nothing. This is the first time I can recall seeing it this way. So can you start a sentence this way? With le matin? Can this sentence be turned around to start with Le matin?
