Ooh, tomatoes and avocado sounds about right, thanks for that suggestion. The sandwiches were good, except needed more cucumber, which we didn't have.

I liked it! I halved the recipe, and the amount of sauce I ended up with was barely enough to feed two, so you might want to up the tomatoes. Also, I think you could probably lessen the butter, my dad complained that it was "too cheesy". So, you know. :D
