Heat the vegetable oil in a pan and fry all the stuffing ingredients (except the sour cream) using a little stock if required. Set aside. Meanwhile preheat the oven to 190 degrees and line an oven dish with some baking paper.Rinse, de-seed & slice all the peppers in half (lengthwise) and place on the baking paper. Sprinkle with salt, pepper, crushed chili, dried oregano, balsamic and olive oil. Bake until you see the peppers looking a little softer than they were but not cooked through. About 10 minutes.Pour the sour cream into the cabbage mix and give it a good swirl. Remove the peppers from the oven and scoop the cabbage mixture into each one, top off with bits of feta cheese & another drizzle of balsamic. Return to the oven for another 5 to 10 minutes. Grill for 2 minutes.
