Peppadew peppers (sweet piquante peppers) are mildly spiced, with a sweet heat. Look for them packaged in jars near the pickles or loose on your grocer's olive bar. (Don't confuse them for cherry peppers, which are very hot!)
Rinse away the oil that the peppadews were stored in, then place them in a shallow baking dish. Stuff each pepper with about 1/2 teaspoon of cheese and top with breadcrumbs. Spritz with olive oil spray. Broil 1-2 minutes, or until the breadcrumbs are toasted and golden brown.
Add the balsamic vinegar to a small pan set over high heat. Bring to a oil and cook until reduced by 3/4 – about 2 minutes. Drizzle over the peppers.
