Preheat your oven to 375 degrees f.
Add to a medium mixing bowl: the room temperature cream cheese (or Greek yogurt), diced green chillies, cumin, garlic powder, chili powder, and a tiny pinch of sea salt.
Stir until really well combined.
Spray or brush a 9 × 13 baking dish with avocado oil.
Spread about 2/3 of this creamy mixture into the bottom of your prepared baking dish as shown.
Heat oil in a large skillet over medium heat and sauté chicken until golden brown and almost cooked through.
Season with sea salt and pepper to taste.
Add cooked chicken pieces into your baking dish in a single layer, then sprinkle with tomatoes and corn. Spread remaining creamy mixture and top with shredded cheese.
Bake for about 20 minutes, or just until golden-brown and bubbly.
Garnish with diced avocado and fresh chopped cilantro or green onions and enjoy!
