In a large mixing bowl, combine the cauliflower gnocchi, diced bell pepper, zucchini slices, chopped red onion, and cherry tomato halves.
Drizzle the olive oil over the vegetables and gnocchi. Sprinkle garlic powder, Italian seasoning, salt, and pepper over the mix.
Toss everything together until all the ingredients are evenly coated with oil and seasonings.
Spread the mixture in a single layer on a large sheet pan.
Roast in the preheated oven for about 25-30 minutes or until the vegetables are tender and the gnocchi is golden brown, stirring halfway through for even cooking.
In the last five minutes of roasting, add the fresh spinach to the sheet pan and toss everything together lightly.
Remove from the oven and let it cool slightly before serving.
Garnish with fresh basil leaves and sprinkle with grated Parmesan cheese if desired.
Notes
