1️⃣ Preheat your oven to 350°F (175°C). 🔥

2️⃣ In a large oven-safe skillet, heat the olive oil over medium heat. Add the green onions, chili powder, cumin, garlic powder, and dried oregano. Sauté for a couple of minutes until fragrant. 🍲

3️⃣ Add the shredded chicken, cooked brown rice, diced green chiles, fire-roasted tomatoes, corn, green enchilada sauce, and 1/4 cup of the shredded cheddar cheese to the skillet. Stir everything together until well combined. Season with salt and pepper to taste. 🌶️🧂

4️⃣ Once the cheese is melted and everything is heated through, remove the skillet from the heat. Quickly stir in the Greek yogurt until fully incorporated. 🥄

5️⃣ Top the casserole with the remaining shredded cheddar cheese. Bake in the preheated oven for about 15 minutes, or until the cheese is melted and the casserole is hot and bubbly. 🧀⏳

6️⃣ Serve the casserole as is, or top it with diced tomatoes and chopped cilantro if desired. Enjoy! 🍽️
