Seven layer tortilla pie - wonderful vegetarian meal!

  We often have a meatless meal, a bit more economical and often healthier for you.  This recipe for the Seven Layer Tortilla Pie was wonderful all around - appealing to both the eyes as well as the taste buds.  Full of taste, beans and cheese, we added a dollop of sour cream and salads and the meal was complete.
I changed the recipe a bit having black beans and refried beans on hand, not pinto beans.  This served our family of 6 (3 big, 3 little) easily with leftovers for the following days lunch.  Using a springform pan, the "pie" shape was easy to obtain and everything stayed "contained".
Enjoy!
Copied from Allrecipes:
(Having used refried beans and black beans, I did not smash any of the beans).

• 2 (15 ounce) cans pinto beans, drained and rinsed
• 1 cup salsa, divided
• 2 cloves garlic, minced
• 2 tablespoons chopped fresh cilantro
• 1 (15 ounce) can black beans, rinsed and drained
• 1/2 cup chopped tomatoes
• 7 (8 inch) flour tortillas
• 2 cups shredded reduced-fat Cheddar cheese
• 1 cup salsa
• 1/2 cup sour cream

Directions

1. Preheat oven to 400 degrees F (200 degrees C).
2. In a large bowl, mash pinto beans. Stir in 3/4 cup salsa and garlic.
3. In a separate bowl, mix together 1/4 cup salsa, cilantro, black beans and tomatoes.
4. Place 1 tortilla in a pie plate or tart dish. Spread 3/4 cup pinto bean mixture over tortilla to within 1/2 inch of edge. Top with 1/4 cup cheese, and cover with another tortilla. Spread with 2/3 cup black bean mixture, and top with 1/4 cup cheese. Repeat layering twice. Cover with remaining tortilla, and spread with remaining pinto bean mixture and cheese.
