The Cheater's Shepherd's Pie

I had some leftover meatloaf so I crumbled it up, mixed it with some canned tomato sauce, and added some frozen mixed veggies.  Then I added some pepper, gound mustard, and some ground garlic.  After I mixed it all, I put it in a casserole dish and spread hashbrowns on top (I used the refridgerated kind).  Then I sprinkled salt, pepper, and some butter on top and cooked it for about 30 minutes.  It was very easy, very good, and nobody complained about leftovers!
