Combine sugar, flour, and salt. Stir in pineapple juice and eggs. Thicken over medium heat, stirring constantly. When thickened, remove from heat and stir in lemon juice. Cool completely before mixing with salad.
Add cooled pasta, frog sauce, and remaining ingredients together. Mix well and serve.
Tami prefers adding additional fruits like apples, bananas, strawberries, etc. Just about any of your favorites will work.
