Preheat oven to 425 degrees.
On a rimmed quarter baking sheet, combined frozen cauliflower gnocchi, zucchini, squash, mushrooms, tomatoes and sausage. Drizzle ingredients with olive oil and season with garlic powder, onion powder, oregano, and salt and pepper.
Roast in the oven for about 30-35 minutes, tossing all of the ingredients with a large spatula 1-2 times to ensure even cooking. Broil for the last 2-3 minutes until the gnocchi and vegetables have a warm, toasted brown finish.
Remove from oven and garnish with fresh parsley and parmesan cheese, and serve with a dollop of ricotta cheese on top.
