Slice the sausages into ½-inch thick slices. Prepare the vegetables by cutting them as well.
Add the sausages and vegetables to a parchment-lined baking tray or an oven-safe skillet.
Drizzle olive oil on top and pour red wine.
Add minced garlic and season with dried oregano. Dried basil, sugar, red pepper flakes, black pepper, and salt.
Mix well so that everything is well combined. Now spread the mixture across the area of the baking tray so that it makes a single layer.
Place the baking tray in a preheated oven at 400-degree F for about 30 minutes or until everything is cooked through. Make sure you toss the ingredients after every 10 minutes.
Once everything is cooked through, remove the baking tray from the oven.
Garnish the dish with freshly chopped parsley and serve the dish immediately. Enjoy!
