In a large skillet, brown the sausages for 3 minutes on each side in the olive oil. Remove sausages from skillet and set aside.
In the same skillet, add the peppers and onions and salt and pepper. Cook veggies for 5 minutes. Add the garlic, tomato paste and wine. Cook on medium heat for 5 more minutes stirring frequently.
Add the can of tomatoes to the peppers and onions and stir to combine.
Return the sausages to the pan, nestling them in the veggies. Cover the pan and simmer on low heat for 10 to 15 minutes or until sausages are cooked through.
