I have left out the sugar and substituted no-fat cream cheese and this recipe turns out just fine.

1	lrg can	Pineapple with juice
1/2	cup	Sugar (can omit or adjust to taste)
2	cups	Boiling water
2	3 oz pkgs	Lime jello
2	2 oz pkg	Dream whip, whipped
1	9 oz pkg	Cream cheese, cut into small cubes
1	cup	Chopped pecans

• Bring pineapple, juice, sugar, and water to boil.
• Add jello and stir until dissolved.
• Chill until it starts getting thick, then add the Dream Whip, cream cheese, and pecans. Mix well, then chill well. It turns out fluffy. I leave out the sugar and substitute no-fat cream cheese and it turns out just fine.
