I made this over the weekend. It was fantastic. Not a low cal salad but everyone who tried it loved it.

5 pounds red potatoes
olive oil
4 cloves crushed garlic
salt and pepper
1 large white onion diced and sauteed
1 pound bacon diced and fried till crispy
1 large bottle kens blue cheese dressing

toss the potatoes with the oil and garlic and salt and pepper, roast on a cookie sheet till soft. Mine took about 45 minutes at 350.
while they are roasting, saute the onion and fry the bacon. when the potatoes are warm mix all together and toss with the dressing.
