Roasted Bell Pepper Salad

Green bell peppers were on sale so I used red and green. If red bell peppers aren't too expensive, you can use two red bell peppers.
You will need
2 Bell Peppers
Onion
Red wine vinegar
Oil
Avocado
Salt and pepper
Place washed bell peppers on the burners of a gas stove and blacken. Keep turning them until they are black. Rinse and peel off the blackened portion. Cut into slices. Slice Onion and avocado. Mix Oil and vinegar. Toss together and add salt and pepper to taste.
