Preheat oven to 400 degrees.
Heat 2 tbsp of olive oil in the oven-safe skillet. Add the onions and green beans. Season with a little salt and pepper. Cook for 2-3 minutes until the beans start to get a little soft and the onions are translucent. Once done, remove from the skillet, cover and set aside until later.
Heat the remaining olive oil to the same skillet. Add the ground turkey and season with a little more salt. Cook, breaking apart occasionally, until browned.
Add the seasoning and mix all together.
Add the diced tomatoes and pinto beans and mix. Add back the cooked green beans too. Cook until heated through, about 1-2 minutes.
Add the crushed blue corn tortillas but do not mix. Then add the shredded cheddar cheese right on top.
Take the oven-safe skillet and place right into the pre-heated oven. Be sure to remove anything that is not oven-safe (like a silicon handle). Bake for 15 minutes or until the cheddar melts. Serve hot in a bowl.
