Pepperoni is tops when it comes to pizza toppings.  Nearly two-thirds of respondents in a new Boboli Pizza Survey say the spicy salami is what they prefer on their pies. More than half also like mushrooms, which is a favorite of 52-percent.  Two out of five like onions on their pizzas, while 37-percent prefer peppers.

Spinach is also popular, especially with the under 25 crowd.  Nearly 30-percent of those 18 to 24 say they like the leafy green vegetable on their pizzas, along with 17-percent of those 25 and older.  But regardless of the toppings, 43-percent

say the most important component to a pizza is the crust.  Just 21-percent think the toppings are what make the pizza, and 13-percent believe the cheese is the key ingredient.
