Preheat the oven to 180 °C. Lightly grease a 6 large hole non-stick muffin pan with oil spray.
Heat olive oil in a medium size saucepan over medium heat. Add onion and garlic. Cook, stirring, for 2 to 3 minutes or until soft. Add capsicum, carrot and chilli powder. Cook, stirring occasionally, for 2 to 3 minutes or until capsicum is just tender.
Add diced tomatoes, beans, and corn. Bring to the boil. Reduce heat to low. Simmer for 4-5 minutes or until the mixture has slightly thickened. Set aside.
Microwave tortillas for 20 seconds to soften. Ease one tortilla into each muffin hole.
Fill tortillas with bean mix and evenly sprinkle cheese over the tortilla pies.
Bake for 10 minutes, until bubbling and golden. Top with coriander sprigs to serve.
