Peel 4-5 medium red potatoes. Slice them into chips about 1/4" thick. Put in a 2 qt. casserole sprayed with Pam. You can dice a small onion and add if you wish. Sprinkle with a tsp. of salt and 1/2 tsp. pepper over the top. Add enough milk to cover potatoes. Add 2 heaping TBSP of flour. Stir everything with a spoon until well mixed. Put 2 TBSP Parkay over the top and bake 375 degrees for one hour. Test with a fork to make sure they're done. Don't cover with a lid or they will cook out.
