Buffalo Chicken Nachos

1.) Preheat oven to 350 degrees F.
2.) Fill a small pot halfway full with water. Bring to a boil, add the chicken, then lower the heat to a simmer. Cook for 7-8 minutes, or until the chicken reaches 165 degrees F. Remove chicken to a bowl and shred it with two forks. Pour in the wing sauce and set aside.
3.) In a small casserole dish (or oven-safe plate), add half of the tortilla chips. Top with half of the shredded chicken, half of the cheddar, and half of the blue cheese. Scatter the other half of the chips on top. Layer on the remaining chicken, cheddar, and blue cheese.
4.) Bake for 10 minutes, or until cheese melts and chicken is heated through. Top with the sliced green onion and a dollop of sour cream.
