Delicious as a side dish, as part of an antipasto, and also wonderful in sandwiches the next day because of its sweet/mellow flavour. 

Ingredients

5 red bell peppers

2 small garlic cloves, very thinly sliced

2 tablespoons extra-virgin olive oil

1 tablespoon finely chopped fresh oregano

3/4 teaspoon coarse sea salt

1/4 teaspoon black pepper

Directions

1. Prepare grill for cooking. If using a charcoal grill, open vents on bottom of grill, then light charcoal. Charcoal fire is hot when you can hold your hand 5 inches above rack for 1 to 2 seconds. If using a gas grill, preheat burners on high, covered, 10 minutes, then reduce heat to moderately high.
2. Lay bell peppers on their sides on lightly oiled grill rack and roast, turning occasionally with tongs, until skins are blackened, 10 to 12 minutes.
3. Transfer to a bowl, then cover and let steam 10 minutes. Peel and seed peppers (reserving juices), then cut into 1/4-inch-thick strips.
4. Stir together peppers (with their juices), garlic, oil, vinegar, oregano, sea salt, and pepper and marinate 30 minutes at room temperature.
