Texas Country Potato Salad

my Mom's cousin gave me this recipe. It is *so good* and so easy, but is not a healthy recipe by any stretch of the imagination. Is easy to triple since potatoes come in a 3lb bag ;)

Texas Country Potato Salad

4 strips bacon
1 pound small red potatoes, unpeeled
1 green onion, sliced
1 boiled egg, chopped
1/4 c mayonnaise
1 t Dijon mustard
salt and pepper

Cook bacon until crispy. Drain, reserving a few tablespoons of the grease, and crumble. Set aside.Place the potatoes in a large saucepan. Cover with cold water. Add a tablespoon of the bacon grease and some salt and place over medium-high heat. (I have omitted the grease before and it turns out okay, just not quite so good) Bring to a boil and cook until the potatoes are tender, about 15-20 minutes. Drain and let the potatoes cool and then cut into bite-size pieces.In a separate bowl, mix mayonnaise, Dijon mustard, salt and pepper for dressing.Toss potatoes, onion and egg in dressing Add bacon. Serve chilled. Even better if you make it the day before you serve it.
