Tortilla Towers

2 teaspoons chili powder
1 cup low-fat sour cream or soy sour cream
1 15-ounce can vegetarian refried beans
1 15-ounce can black beans, drained and rinsed
1 medium tomato, chopped
1/4 (one-quarter) cup sliced black olives, drained
1 cup shredded low-fat cheddar cheese or soy cheese
1 large avocado, peeled, seeded and chopped
1/4 (one-quarter) cup green onion, thinly sliced with tops
6 six-inch whole wheat flour tortillas

In small bowl, mix chili powder with sour cream and set aside. Place one tortilla on plate and top with one-quarter of the refried beans, black beans, tomatoes, olives, cheese, avocado, sour cream and green onion. Arrange toppings towards the outside edge of tortilla so the tower looks flat. Repeat layers starting with another tortilla and ending with a tortilla. On another plate, prepare a second tower. Wrap both with plastic wrap and refrigerate until ready to serve. When ready to serve, slice into wedges. Top wedges with spoonful of salsa. Yields 12 servings.
