Order this! The Parmesan Crusted Tilapia is a must order when at Olive Garden. The large portion of fish is cooked to perfection and the saltiness of the parmesan is wonderful. It is one of the lower calorie items on the menu as well - 590 calories is so worth it! The Tour of Italy boosts 1450 calories! Wowza. Order a glass of chardonnay and enjoy your fish!
