All you need is...
Slice the Zucchini into round sections...not too thick but thick enough that they don't cook too fast.
Slice the green part of the scallions.
Pour a little Olive Oil in the pan...add the Zucchini and scallions and throw in some garlic salt.
Cover the pan, stirring often. Cook until the zucchini is softened.
Add a little salt and pepper to your own serving (if you want)
There really is no set measurements and I think that's what I like the best.
