What's for dinner?

Ok...So I wasn't quite sure what to make for dinner the other night.  I was thinking mexican and didn't have any lettuce for our usual tacos, and really I wanted something different.   So I came up with this....
Mexican lasagna or Mexican Casserole ??
2lb. Ground beef
2pks taco seasoning
8 or 10 in soft taco shells
2 cups any kind of shredded cheese (I used pepper jack)
Corn chips

Brown your meat then add taco seasoning and 1cup of water
Spray a casserole dish with cooking spray then place 2 soft taco shells on the bottom then layer with meat next cheese....continue untill there is no meat left... (mine made 2 layers)
Top with cheese and crunched up corn chips and bake at 350 for about 20 min or untill cheese has melted.

I served mine with sour cream on top ;-)
(I think it would have been good to layer the sour cream in before baking aswell)
