Start by chopping the green onions. The white parts of the green onion will be cooked in the pan, while the green parts will be used to garnish on top. Then, chop an onion into tiny pieces.

Heat a large pan and spray it lightly with oil. Sauté the onions in the pan until they are translucent. Then, move the onions to one side of the pan and add the ground chicken breast. Season the chicken breast with salt, pepper, garlic powder, and taco seasoning. Break up the chicken into smaller pieces and make sure it is thoroughly cooked.

After the ground chicken is cooked, it's time to assemble the enchiladas! Cut the tortillas so they fit in the baking dish. Then, add enchilada sauce to the baking dish and make sure it covers the entire bottom of the dish. After that, cover the sauce with tortillas. Next, add the chicken, some more sauce, some cheese, and add another layer of tortillas. Then, add more enchilada sauce to the top of the tortillas. Make sure to cover the tortillas with sauce so they don't dry out or burn in the oven. Then, add chicken and cheese, more tortillas, the rest of the enchilada sauce, and cheese.
