1Put EVOO into steamer bag. Add salt, pepper, parsley and seasonings. Close bag and mash bottom of bag to dissolve and distribute seasonings into oil, add a bit more oil if you need to. Add potatoes, onion, garlic and about a tablespoon of butter. Seal bag and cook on high in microwave for 7 minutes. Carefully shake bag, cook 7 more minutes. Shake again and continue to cook for 5 more minutes. (The instructions say to cook 14 minutes, but I add an additional 5 minutes.) Open bag (careful, it's steamy) and pour potatoes into serving bowl, add cheeses and butter, carefully - so as not to mash potatoes - mix to melt cheeses and butter into potatoes. Top with bacon pieces, sour cream or your choice of toppings. NOTE: When you can find a smoked cheese, that's really good, too, it gives the potatoes a really good smoky flavor, I have cut up smoked sausage and cooked in bag with potatoes, yumm. If I'm cooking corn, broccoli, etc. for that particular meal, I'll re-use the same bag and steam that, too.
