Start water heating to a boil for tortellini as indicated on tortellini instructions.
In a large saucepan, heat tomatoes, tomato sauce, and broth to a simmer.
When water is boiling, cook tortellini according to package directions. Set aside.
Add garlic salt, basil, and sugar to tomato soup base. Simmer for 5 minutes, stirring occasionally. Reduce heat and add the half and half and the butter sections.
Heat, stirring regularly, until butter is melted and soup is hot but not boiling.
Add cooked tortellini and spinach and stir gently. Cook over medium heat for about 2 minutes or until spinach is wilted and tortellini is hot.
Season to taste with salt and pepper and serve immediately.
