Preheat the Bull Grill to low-medium. Lightly spray bread with olive oil. Place bread on grill for a few minutes to slightly crisp it.
Toss tomatoes and bell peppers in a little olive oil and grill for 10 minutes or until they have grill marks on them. Remove from heat and allow to cool.
Gently combine all ingredients together and toss until they are thoroughly incorporated. Drizzle with olive oil and season to taste.
