Bring a large pot of salted water to a boil. Add the tortellini and cook according to the package instructions. Once cooked, drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add minced garlic and sauté for about 1 minute until fragrant, being careful not to burn it.
Pour in the diced tomatoes (with juice) and stir. Let it simmer on low for 3-5 minutes to combine flavors.
Slowly add the heavy cream to the skillet, mixing well to create a creamy sauce.
Sprinkle in the dried basil and oregano, and season with salt and pepper. Stir until well combined and allow it to cook on low for another 3-4 minutes.
Add the fresh spinach to the sauce and stir until wilted and incorporated.
Gently fold in the cooked tortellini to the sauce until well coated. Cook for an additional 2 minutes over low heat to warm everything through.
Serve immediately, topped with grated Parmesan cheese and fresh basil leaves for garnish.
