Queso Baked Nachos

Directions

1. Preheat oven to 350°. In a large skillet, cook and crumble beef over medium heat until no longer pink, 5-7 minutes; drain. Stir in taco seasoning and water; bring to a boil. Reduce heat; simmer, uncovered, until thickened, about 5 minutes, stirring occasionally.
2. In an ungreased 13x9-in. baking pan, layer a third each of the chips, beans, beef mixture and queso dip. Repeat layers twice.
3. Bake, uncovered, until heated through, 10-15 minutes. Top with tomatoes, and chives if desired; serve immediately with sour cream on the side.
