I use garlic powder instead of garlic salt, less sodium. Sometimes I'll put some freshly grated parmesan, other times some Italian seasonings. A friend of mine puts pesto on the bread and then adds a thick layer of shredded Monterey Jack cheese. (This was before her WW days! )
I use I Can't Believe Its Not Butter all the time, but then I'm not watching out for those oils either.
Whatever I put on it, I do the same thing, spread it, sprinkle it and then broil it.
