🚨🍕 UNDERCOVER FLAVOR ALERT 🍕🚨

Meet The Sting Operation 🐝🔥

This slice is working deep undercover to steal your taste buds.

Loaded with: Honey Hot Sauce, Fresh Jalapeños, Fresh Basil, Crispy Cupped Pepperoni, & Creamy Ricotta

Sweet. Spicy. Savory. Every bite is part of the mission.

The only thing we’re investigating is how something this good disappeared so fast.
