Italian Sausage Heroes with Peppers and Onions

1. In a large skillet, heat 1/4 cup of the olive oil. Add the onions and cook over high heat, stirring frequently, until golden, 10 minutes. Stir in the paprika, sugar and red and green bell peppers. Reduce the heat to moderate and cook, stirring occasionally, until the peppers are softened, about 12 minutes. Stir in the water and oregano. Season with salt and pepper, cover and keep warm.
2. Meanwhile, heat the remaining 1 tablespoon of olive oil in a medium skillet. Prick the sausages all over, add them to the skillet and cook over moderately high heat, turning frequently, until browned all over, about 5 minutes.
3. Transfer the sausages to a cutting board and halve lengthwise. Return the halves to the skillet and cook over moderately high heat, turning occasionally, until no trace of pink remains within, about 5 minutes. Transfer to a plate.
4. Halve each roll (keep it hinged). Pull out some of the bread within. Toast the rolls.
5. Drizzle the cut sides of the rolls with olive oil and set 2 sausage halves on each roll. Top with the sautéed onions and peppers, close the sandwiches and serve immediately.
