I have three separate ideas, one is kind of nuts, one uses nuts, and one is crazy.
First off, use a stove top smoker with the peppers. I like to pre-roast the chillis with this darn thing. Smoke all the peppers whole, then add the tomatoes and vinegar and other stuff.

Second, add cashews. I know I am getting crazier here, but it does work Pulverize the heck out of them, mix them with tomato paste, and work it in.
Now we get to crazy, you were warned. Foraged greens. Dandilions blackberry greens and ramps. These are bitter on general principal, as they don't like to be eaten by deer and livestock, but when combined with tomatoes, and you might sometimes add a tbsp of honey or maple, can taste nice.
Ill advised, nuts and crazy, I do deliver what I promise.
