Place 2 roasted peppers in a food processor or blender, and process until smooth. Chop remaining roasted peppers.
Bring water and broth to a simmer in a medium saucepan (do not boil). Keep warm over low heat.
Heat the oil in a large saucepan over medium-high heat.
Add onion; saut 3 minutes or until tender.
Add rice; cook 2 minutes, stirring constantly. Stir in wine; cook 2 minutes or until the liquid is nearly absorbed, stirring constantly.
Add broth mixture, 1/2 cup at a time, stirring constantly until each portion of broth is absorbed before adding the next (about 20 minutes total). Stir in pureed and chopped peppers, and cook 2 minutes, stirring constantly.
Remove from heat; stir in Parmesan cheese and the remaining ingredients.
