In a large skillet, heat the olive oil over medium heat. Add the sausage links and cook until browned on all sides, about 8-10 minutes.

Remove the sausage from the skillet and slice them into bite-sized pieces.

In the same skillet, add the sliced onion and bell peppers. Sauté for about 5 minutes until they begin to soften.

Add the minced garlic, Italian seasoning, salt, and black pepper. Cook for an additional 2-3 minutes until fragrant.

Return the sliced sausage to the skillet and stir to combine with the vegetables. Cook for another 5-7 minutes until everything is heated through.

Serve hot, optionally with crusty bread or over pasta.
