I don't know what they're really called. But she cuts the peppers in half, scoops out the insides and fills the hull with sour cream, parmesan cheese and pan sausage. They're really delicious.
I say this because I wanted to make a brief comment about parmesan cheese. I had always thought I didn't like it. Until, that is, she began making these things and had to buy some real parmesan to do it. That is, parmesan that comes in a big block and requires grating. That stuff is excellent. I don't know who came up with the idea that something called "parmesan" should be powdered, sold in shaker containers and apparently flavored with skunk scent, but they should be severely punished. Nastiest stuff I've ever tried to flavor food with.
In case you've never had actual parmesan, you should. But then of course you'll never want to eat that powdered cr*p again.
