Preheat oven to 400 ℉.

Prepare 4 individual baking dishes or 1 larger, around 9x13-inches by lightly greasing with cooking spray or oil.

Place tomatoes, garlic, basil, and evoo in the dishes. Sprinkle with salt and pepper and toss well. Place in oven to roast while you prepare the gnudi.

In a large bowl, combine spinach, ricotta, parmesan and flour. Mix well. Add salt and pepper to taste.

When tomatoes begin to soften, remove pan from oven and use a large tablespoon to form the gnudi. Scoop mixture into the palm of your hands and form into compact ovals. Place on top of tomatoes. Repeat with remaining mixture, you should have about 16 gnudi.

Sprinkle with additional Parmesan cheese and bake uncovered for about 25 minutes. Serve with bread or pasta.
