How to Make It
Place tortillas in a single layer on baking sheets; brush with butter.
Bake at 400° for 4 to 5 minutes or until lightly browned.
Combine chicken, tomato, and chiles; spoon evenly onto tortillas. Top evenly with cheeses and green onions; sprinkle with paprika, if desired. Bake 3 to 4 more minutes or until cheeses melt. Serve with sour cream.
