Preheat the oven to 350 degrees F. Lightly grease a 2-quart casserole dish with 1 teaspoon of olive oil.
Bring a medium pot of water to a boil. Add 1 teaspoon of the salt and the pasta shells, and cook until al dente, 10 to 12 minutes, stirring occasionally with a long-handled spoon to prevent the shells from sticking together. Drain and rinse under cold running water. Drain.
In a medium skillet, heat the remaining tablespoon of olive oil over medium heat. Add the onions and garlic and cook, stirring, until very soft, 6 to 7 minutes. Add the ground veal and cook, stirring, until cooked and browned. Add the squeezed spinach and cook, stirring, for 3 minutes. Remove from the heat and season with salt and pepper.
In a large bowl, combine the ricotta cheese, eggs, Parmesan cheese, and 1 cup of the mozzarella cheese. Add the spinach mixture, the extra-virgin olive oil, Essence, remaining teaspoon of salt, the basil, oregano, and pepper, and stir to combine thoroughly. Spoon about 2 tablespoons of the spinach-ricotta filling into each cooked pasta shell. Place the filled shells in the prepared dish.
Pour the Basic Red Sauce over the filled shells and top with the remaining 1 cup of mozzarella cheese. Bake, uncovered, until bubbly, about 20 minutes. Remove from the oven and let rest for 5 minutes before serving.
