I spent $1.99 very wisely a few weeks ago: I bought a box of slow cooker liners (found in the paper goods aisle, by the Saran Wrap). There were 4 in the box, so $0.50 a piece.
In another bowl, I whisked together 1 can of cream of mushroom soup, a packet of brown gravy mix, and about 3/4 cup of water.
I poured the mixture over the round steak, put the lid on, and left for the day!
That night, I made a big green salad and boiled some wide egg noodles. I took a couple of forks and kind of broke up the steak (it's so tender by this point that it just falls apart).
And here's the beauty of it:
(and a really great picture, too!) The bag didn't break or leak at all, my Crock Pot is just really ugly, it gets used A LOT!
You may be wondering where Rex has been residing these days... Well, he hasn't spent the night in his kennel since the cold snap. Dave puts him in the kennel in the morning and the kids let him out when they get off the bus, then we let him in the house when it gets dark. He's even got his own job! (Just kidding!)
