Wash the bell peppers and slice into thin strips. Cut the red onion into strips as well.
4 green bell peppers, 1/2 red onion
In a large frying pan, heat the olive oil and saute the red onion until softened, approximately 5 minutes.
2 tbsp (30 mL) olive oil
Add the peppers to the pan and continue to cook, stirring regularly, for approximately 5 minutes. Add the parsley, oregano, salt and pepper. Cook for an additional 5 minutes.
2 tbsp chopped fresh parsley, 1 tsp dry oregano, 1/2 tsp salt, 1/4 tsp ground black pepper
Add the red wine vinegar to the skillet. Stir and cook for an additional 3 - 5 minutes. You want your green peppers to be caramelized in some areas.
1 tbsp (15 mL) red wine vinegar
Transfer to a serving platter and sprinkle with some fresh parsley if desired.
Enjoy!
