Wakame Strudel

[Kali]

Lost my recipe for wakame strudel and wonder if anybody has one. It's technically not a strudel dough, but is shaped like strudel. The crust was a little crumbly with cornmeal in it (and maybe toasted sesame seeds?), and the filling was wakame, green onion, and I think a mashed umeboshi plum but i don't remember what else, if anything. The wakame was meltingly tender and delicious, almost creamy in texture, and I wonder if there could have been tahini in it but I think not. I'm getting hungry just writing this. Would be very grateful if anyone has this recipe or could suggest how to recreate it.

Thanks!
