Topping dolloped on fresh Italian tomatoes, maybe

PESTO

Think of a vibrant green sauce made with basil, garlic, and pine nuts—often paired with mozzarella in a classic Caprese dish.

This clue hints at a sauce often paired with fresh tomatoes in Italian dishes. "Dolloped" suggests a thick, spoonable topping, and "pesto" fits as a classic green sauce made from basil, garlic, and pine nuts. The "maybe" leaves room for other toppings but points to pesto as the most likely answer.
