7-Layer dip or Taco Casserole

My friend makes this and serves for dinner. I never thought of 7-layer dip as a maindish, but it was fabulous!

7-layer dip:

1 lb ground beef
1/2 package taco seasoning
1 can refried beans
1 c. sour cream
8 oz. cream cheese
1 can diced tomatoes
salsa (I replaced the tomatoes and salsa with a can of Rotel)
1 container guacamole (I make mine homemade)
mozzarella
black olives
Tortilla chips or wraps

Brown 1 lb ground beef and drain.
Add about 1/2 pkg taco seasoning (no water, though).
Meanwhile, spread 1 can refried beans into 9x13 pan.
Ground beef goes on top of that.
Mix together 1 c. sour cream with 8 oz cream cheese and then spread on top.
Next goes on 1 can diced tomatoes (drained) plus some salsa (as desired).
Then 1 container of guacamole
Top with mozzarella and sliced olives.

Bake 350 for 30min.

I like to serve with Hint of Lime chips, but my hubby likes to scoop his out into a tortilla for a burrito.
