What bread-based appetizer features a variety of toppings at Olive Garden?

Bruschetta is correctly identified as the bread-based appetizer featuring a variety of toppings at Olive Garden. This dish typically consists of toasted bread slices topped with a mixture that can include ingredients like diced tomatoes, basil, garlic, and balsamic glaze. The variety of toppings not only provides a burst of flavor but also showcases Mediterranean influences, making it a popular choice for guests looking for a fresh and savory appetizer. Variations may also include other toppings, but the essence of bruschetta is its use of bread as a base embellished with different flavorful ingredients.

In contrast, garlic breadsticks, while also a beloved menu item, do not feature a variety of toppings but are instead known for their garlic flavor. Stuffed mushrooms are more focused on the filling, which typically includes cheese and herbs, and do not utilize a bread base in the same way. Fried calamari is a seafood dish that does not involve bread as a base appetizer. Thus, bruschetta stands out as the option that embodies the combination of bread with diverse toppings.
