Beat sugar, oil, and eggs together well. Add vanilla. Sift flour, salt, baking soda, and nutmeg together. Add chopped apples to sugar mixture and beat well. Stir in flour mixture and nuts. Pour batter into greased and floured 2-pound coffee can. Place in slow cooker; cover top of can with 4 to 6 paper towels. Cover and cook on high about 3 1/2 hours. Cooker lid should be slightly raised to allow excess moisture to escape. Add no water, and don't peek until last hour.
