"Slop" Recipe - My husband's Favorite!

I received this recipe from my mother-n-law.  She made it for him when he was a boy.  I believe she called it Tater Tot Casserole (sounds more appropriate) but we always like to change things up and my husband titles it "Slop" because it's a big mess and he absolutely loves it.  What's not to love - meat, potatoes, cheese?  And it's quick and easy!

Slop Recipe:

1.5lbs - 2lbs. ground beef (hamburger, or you can substitute with turkey burger, which I do often).
1 small onion (or substitute with dried, minced onions-see label for amount)
1 can of cream of mushroom soup (or 98% fat free mushroom soup)
1 soup can of milk
1 can of mushrooms (large or small, depending on what you prefer - or none:)
1 bag of tater tots
8oz. of mozzarella cheese
Salt/Pepper
9 x 13 pan

Pre-heat oven to 400 degrees
Flatten hamburger or turkey burger on the bottom of pan
Add onions all over
Spread Cream of Mushroom Soup over top, then pour 1 soup can of milk over it (or mix both together and put in - either way).
Add mushrooms (layer)
Add 1 bag of tater tots (layer on top)
Add a dash of salt and pepper
Put in oven for 1 hour
Add mozzarella cheese and melt (not too long!)

Let cool a little and cut!  Ta-Da!  Yummy, Cheesy, "Slop" Casserole!  My daughter likes ketchup with it and so do I!

Here's a pick...And look?  Someone has already got into it!!!?
