Another one from Gooseberry Patch. The only thing that went wrong for me is that I put everything in the crockpot and then totally forgot to turn it on, went back 3 hours later and nothing. I could have kicked myself, so I ended up having to pop the dish into the oven. *sigh*
1/3 cup Dijon mustard
1/2 c. olive oil
1/3 c. red wine vinegar
salt and pepper to taste
6 potatoes, cubed
1 onion, chopped
Blend mustard, oil and vinegar in a medium bowl; add salt and pepper to taste. Add potatoes and onion, stirring to coat.
Transfer to a slow cooker; cover and cook on low setting for 8 to 10 hours, or until potatoes are tender. Makes 4 to 5 servings.
