I have made these, with shop bought tortillas, and while the flavours of the chicken mixture are fantastic, I didn't like the soggy texture of the tortillas. When I made it again, (as it was so yummy!), I used rolled up lasagne sheets instead of the tortillas. Next time, I'll try filling canneloni tubes if I can find large ones. It would be too fiddly with normal size ones.
I like the idea of rolled up lasagne sheets. Thanks.
