Which salad ingredient belongs to the same family as deadly nightshade?

The salad ingredient that belongs to the same family as deadly nightshade is tomato.

Both tomatoes and deadly nightshade belong to the *Solanaceae* family, also known as the nightshade family. This family contains a wide variety of plants, including many edible ones like potatoes, peppers, eggplant, and even tobacco.

While tomatoes are safe to eat, it's important to remember that many plants in the nightshade family contain toxic alkaloids. These alkaloids are concentrated in the leaves and stems of the plants, so it's crucial to only consume the fruits or vegetables specifically designed for eating.
