Thrifty Menu: Crockpot Potatoes and Roast Beef

I had about 1/3 a pound of shaved roast beef left over from sandwiches.  It seems once we have sandwich night, no one wants to have them again for a few weeks.  I always try to purchase just enough deli meat for the occasion, but sometimes left-overs happen.

I knew I wanted to do something different, not traditional pot roast or hash.  I did some research.  What I put together was a combination of a couple different recipes. I also knew I wanted to throw it all into a crockpot.

Here's what I came up with.

Crockpot Potatoes and Roast Beef

2 medium potatoes
1/3 cup shaved roast beef
1/2 cup chopped onions

1/2 cup butter
1/2 Tab chopped garlic
1/2 Tab flour
1/4 Tab chopped parsley
1/2 Tab mustard
salt, pepper
1/2 cup water

Coat crock pot with non-stick spray.
Peel potatoes; thinly slice.  Layer in crock-pot.

In skillet, melt butter.  Add chopped onions, garlic, parsley and salt / pepper.  Stir together and cook until onions are tender.
Add water and mustard and stir until well blended.
Add shaved roast beef and cook until covered.  If the mix is too thick, add water.

Pour over sliced potatoes in crockpot and cook on high for 1-2 hours.

Before serving, sprinkle with shredded mozzarella
or provolone cheese.
