1 Preheat oven to 375°F. Arrange chips in single layer on 2 lightly greased foil-lined shallow baking pans, overlapping chips if needed to cover pan completely.
2 Mix refried beans, sour cream and Seasoning Mix in small saucepan. Cook on medium heat until heated through, stirring occasionally. Spread 1/2 of the refried beans mixture on each pan of chips. Sprinkle each with 1/2 of the cheese.
3 Bake 5 minutes or until cheese is melted. Sprinkle with tomatoes and green onions. Serve immediately with assorted toppings, if desired.
