Stir in the flour and seasonings (salt, pepper, cumin, garlic powder, chili powder).
3 tbsp all-purpose flour, 1/4 tsp salt, 1/4 tsp black pepper, 1 tsp cumin, 1 tsp garlic powder, 1 tsp chili powder
Cook for 1 minute to remove the raw flour taste.
Slowly whisk in the chicken broth until smooth and slightly thickened.

Mix until well combined.
Cut the tortillas into quarters and fold them into the skillet, coating them in the sauce.

Spread evenly in the skillet.
Place in the oven and bake uncovered for 10 minutes.
Remove and sprinkle with the shredded Monterey Jack cheese. Return to the oven for another 5 minutes, or until the cheese is melted and bubbly.

For a golden top, broil for 1 minute.
Remove from the oven and let cool slightly before serving.
