1 large head cabbage 
2 large bell peppers, frozen
1 large Vidalia onion
1 1/2 cups mayonnaise (I use Bama Mayonnaise.)  
1 cup Splenda
1/2-3/4 teaspoon garlic powder 
Salt
Pepper 

Using a chopper, finely mince the cabbage and set aside in bowl. Place one frozen bell pepper and half of the onion in the chopper. Chop until the mixture is almost liquid. Add to bowl with cabbage. Repeat with remaining pepper and onion. Add to chopped cabbage, along with mayonnaise, Splenda, garlic powder, salt and pepper. Mix well. Taste and add more salt, pepper or Splenda if needed.
