Pre-heat the oven to 400 degrees.
Line a baking sheet with aluminum foil. Spray the aluminum foil with a generous coat of non-stick cooking spray.
Chop the broccoli, cauliflower, and chicken sausage into bite-sized pieces.
Arrange the vegetables, gnocchi, and sausage in an even layer on the prepared baking sheet. Coat them generously with extra virgin olive oil.
Sprinkle the entire pan generously with garlic pepper. Finish the vegetables, gnocchi, and sausage with salt and pepper to taste.
Bake for 15-20 minutes, stirring once during cooking. I stir at 10 minutes and then check again at 15 minutes. You want the gnocchi to be crispy and the vegetables and chicken sausage to be browned but not burnt.
Serve immediately.
