Margarita Cheesecake Bars

These tasted good but the cream cheese was really hard to spread on the cake. it kept tearing the cake--even after i heated it a little bit. I think i'd like to try them again with a marshmallow and cream cheese frosting.

2 egg whites
1 c. water
½ c. unsweetened applesauce .3 oz package sugar free lime jello
