I had a lot of non-bell sweet peppers. They look like the photo below. After browning some hot Italian sausage, I sauteed the peppers with a red onion and three smallish roma tomatoes that I happened to have on hand. I was not going to use any tomato, but am glad I used them. Then I added a bit of water...like a cup....and some vegetable BTB (Better-than-Bouillon) and let it all cook down. Added a touch more water and a scant tablespoon of tomato paste. It was very flavorful. In hindsight, I would not cook down the peppers quite so much as I think they would be great with a little bit of body to them - but the sauce was good!
I did not add salt, but did add black pepper. I'm not big on salt. I wish I knew what peppers these were. They were simply called "sweet pepper". They grow about as large as my hand in length and sometimes as wide as my palm. And pick them today and you will get 2x as many tomorrow! Obviously, they do not care if they are not weeded regularly.
