Preheat oven to 350FÂș. Wrap the red bell peppers in foil and roast in the oven for 30-35 minutes. Check the red pepper after 20 minutes or so, every oven is different so yours may cook faster and need less than 30 minutes. If the peppers are soft and beginning to blister, leave them uncovered, put them back in the oven and roast for another 5-7 minutes, until slightly charred. You want your peppers to be very soft. Take out of the oven and let cool.
Finely chopped the peppers and put them in a bowl. Add olive oil, capers, olives, freshly ground peppers and mix well.
A yummy way to serve this spread is by lightly toasting a baguette, putting a little bit of the spread on top and sprinkling a little freshly grated parmesan.
