Enchilada Bake

My take on a recipe found in the church cookbook A Taste of Up North.

Ingredients:
1 package 10 count tortillas
1 lb ground beef
1 can (16 oz) refried beans
1 medium onion, chopped
2 garlic cloves, chopped
1 can (14.5 oz) corn
1 can (2.25 oz) sliced olives
1 can (20 oz) enchilada sauce
2 cups shredded cheese
Sour cream

Cook beef, onion, & garlic over medium-high heat; drain fat
Add beans & corn; mix well
Fill tortillas with meat mixture & roll up
Place in 9"x13" pan, seam sides down
Pour enchilada sauce over top
Add shredded cheese & olives
Bake at 350º for 3o mins or until cheese is melted & heated through
Top with sour cream if desired
