In a 12-inch skillet, heat olive oil over medium-low heat. Brown sausage links, turning occasionally to ensure they do not burn. Brown until cooked through (10-15 minutes). Remove sausage links to a plate and keep warm.
Slice bell peppers and onion. Add to the skillet and cook over medium heat until slightly browned and onions are soft and translucent (10 minutes).
Add minced garlic to the pan and saute 1-2 minutes more.
Add wine to skillet and scrape browned bits from the pan to deglaze. Bring to a simmer and reduce wine by about half (2-3 minutes).
Add roasted bell peppers, crushed tomatoes, and oregano to the skillet.
Slice sausage links into bite-size pieces and return them to the skillet.
Simmer over medium until everything is warmed and sausage is cooked completely (if it was not thoroughly cooked in step one).
