Heat olive oil in a large skillet over medium heat.
Add ground chicken and cook, breaking it apart with a spoon, until a food thermometer confirms 165°F (74°C). Browning alone does not confirm safe doneness.
Stir in taco seasoning and cook for about 1 minute. Follow the packet directions, including required liquid, and stir to prevent scorching.
Add corn, black beans, and diced tomatoes. Bring to a simmer and cook for 5 minutes, or until heated through.
Serve hot and enjoy!
Notes
Garnish with sour cream, cheese, or avocado for added flavor.
