Heat broiler, with rack in top position. Make a long slit down three-fourths of the length of each pepper, leaving stem attached. Stuff each pepper with 1 slice dried chorizo and place on a rimmed baking sheet. Broil until peppers are blistered and browned on all sides, about 4 minutes, turning peppers frequently. Serve warm or at room temperature.
I used deli chorizo fluted into the peppers that I had only cut the tops and seeds out of. I served on a salad. The oils made for a nice addition to a light splash of olive oil and white wine vinegar.
