01 - Preheat the oven to 350°F. Lightly grease a medium baking dish with olive oil.

04 - In a large bowl, whisk together eggs, heavy cream, ricotta, Parmesan, oregano, black pepper, salt, and nutmeg until smooth and well combined.
05 - Gently fold the cooked spinach mixture and half the cherry tomatoes into the creamy mixture until evenly distributed.
06 - Pour the mixture into the prepared baking dish. Scatter the remaining cherry tomatoes and pine nuts evenly over the top.
07 - Drizzle with the remaining tablespoon of olive oil and sprinkle breadcrumbs over the surface.
08 - Bake for 30-35 minutes, or until golden brown and set in the center.
09 - Allow the bake to cool for 5 minutes before serving to set the texture.
