Dice the tomatoes, grate the mozzarella cheese, and chop the coriander. To a food processor, add the chicken thigh and pulse until it is reduced to a fine mixture. Scrape down the sides and pulse one last time, ensuring the chicken is reduced to a fine mince.
To a medium saucepan over medium-high heat, add the chicken, garlic powder, onion powder, dried oregano, black pepper, chili flakes, ground cumin, chili powder, and salt. Cook for about 6 minutes until the chicken is well cooked.
Turn off the heat, then remove the saucepan from the heat. Add the diced tomatoes, mozzarella cheese, and cream cheese. Toss to combine using a spatula.
Serve warm with low-carb tortilla chips or celery sticks. Garnish with coriander and a crack of black pepper. Store leftover taco dip in an airtight container in the fridge for up to 3 days.
