Tostada Bake

Found this one on Tastebuds. Easy and pretty good. Addie was in love. I liked it, but it was a little salty for me so I think I may used some torn tortillas on the bottom with it next time too to balance out the chips.

1 lb ground beef
1 15oz can tomato sauce
1 pkg taco seasoning
2 1/2 cups Fritos
1 15oz can refried beans (I used FF)
grated cheddar cheese

-Brown ground beef, add half can of tomato sauce and taco seasoning, mix well.
-Line bottom of greased 9x13 pan with 2 cups corn chips. Crush remaining chips, reserve.
-Spoon meat mixture over chips. Combine remaining tomato sauce and refried beans. Spread over meat.
-Bake, covered, at 375 degrees for 25 min.
-Sprinkle with cheese and crushed corn chips. Bake uncovered 5 min
