Cube potatoes into bite-sized pieces and cook on top of stove in boiling water for about 5 minutes, don't boil too much as they will become mushy, I bring the water to a boil, then turn on lower heat, also start boiling potatoes with cold, salted water to prevent "mushiness". Cook just enough to get them started to cooking good in the crockpot. Mix rest of ingredients together. (I slice the onions for the picky ones in my family to pick out, they like things cooked with onions, they just won't eat them.) Put potatoes in crockpot sprayed with cooking spray or use a crockpot liner for easy cleaning. Put other ingredients on top of potatoes. Cook on high until they get good and hot, then turn on low. Stir once while cooking to mix all ingredients well. Cook until tender and slightly thickened. Garnish with parsley flakes or shredded cheese.
