This recipe is great for several reasons. Cheese in a souffle is great; the Parmesan gives it a little kick, and has less calories and fat than many other recipes. I found the recipe to be forgiving; I didn't mix, combine, etc. in exactly the right order, and it still turned out fine. Important thing is to whip the egg whites and fold them in last. It's lovely if you garnish the top with a few rings of sliced peppers about 15 minutes before you take it out. Yes, it does serve two generously. THIS two ate generous portions and gobbled it up at one meal!
