Hi Margaux,
Thanks. I figured you knew what you were talking about, and took it from there. I wasn't and am not about to correct you when it comes to Spanish food terminology. While I'm fluent in Spanish -- including a fair amount of culinary jargon -- I don't have anything like your expertise in Spanish food nomenclature and defer to you.
A roulade is typically braised. If the dishes you called rotis were cooked covered, they could be fairly be described as a roulades -- or at least, "close enough." If not, not.
Other than clarifying some basic definitions for the benefit of others, I don't care too much about names; have no desire to argue these definitions with anyone having already said what I had to say; and am only responding because you wrote specifically to me.
In the end it comes down to what you put on the plate.
