Preheat oven to 180°C. Lightly spray 6 holes of a ⅔-cup (160ml) Texas (large) muffin pan with olive oil spray.
Heat the oil in a medium saucepan over medium heat. Add onion and garlic. Cook, stirring, for 2-3 minutes or until the onion is soft. Add the capsicum, carrot and chilli powder. Cook, stirring occasionally, for 2-3 minutes or until capsicum is just tender.
Add the tomato, beans and corn. Bring to the boil. Reduce heat to low. Simmer for 4-5 minutes or until the mixture thickens.
Place the wraps on a clean work surface. Trim each wrap to a 15cm disc. Place wrap discs on a microwave-safe plate. Heat in microwave for 20 seconds to soften. Place 1 wrap in each prepared hole. Fill with the bean mixture and sprinkle with mozzarella.
Bake for 10-15 minutes or until wraps are crisp and cheese is bubbling and golden. Top with coriander sprigs and serve with lime wedges.
