are tomatoes a member of the nightshade family
Solanaceae The Solanaceae, or nightshades, are an economically important family of flowering plants. The family ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of important agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many, including tomatoes, potatoes, eggplant, bell/chili peppers, and tobacco are widely used. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons).[2] The Solanaceae consists of about 98 genera and some 2,700 species,[3] with a great diversity of habitats, morphology and ecology.
Tomato sauce Italian varieties of tomato sauce range from the very simple pasta al pomodoro to the piquant puttanesca and arrabbiata sauces. Tomato sauce with pasta can stand on its own or it can also be paired with ingredients such as Italian sausage, clams, bacon cubes, tuna, meatballs or vegetables, for a more lively pasta dish.
