How to bake Italian sausage
In a medium-sized bowl, combine the sliced peppers and onion with the olive oil, garlic salt, Italian seasoning, and balsamic vinegar (or syrup). Stir to combine.
Place your Italian sausages on a sheet pan covered with parchment paper. Spread the sausage and veggies mix out so they'll brown during cooking.
Cooking time
Place the entire dish in a pre-heated 400 F oven bake for 15-minutes+, flipping the Italian sausages and stirring the vegetables after 10 minutes.
If you prefer to cook Italian sausage longer to get them darker in color, sausage can continue cooking up to 185-190 degrees Fahrenheit without starting to dry out. They're technically cooked through with an internal temperature of 165 degrees. Or you can do a quick broil at the end as a sneaky trick.
Serve with a simple salad and enjoy!

- You can easily double this recipe to feed a larger crowd, but be sure you use a larger pan to accommodate.
