Sweet N Low Strawberry

Strawberry... I loved this fruit

2 envelopes dietetic strawberry gelatin
1 c. boiling water
1 c. crushed pineapple, in own juice
1 ripe banana, finely diced
6 oz. plain yogurt
1 envelope Sweet'N Low

Dissolve gelatin in boiling water. Add juice drained from pineapple with cold water. Enough cold water to equal 1 cup liquid. Add pineapple and banana. Pour 1/2 into 1 quart bowl. Chill until firm. Spread evenly with plain yogurt mixed with sugar substitute. Place bowl in freezer for 30 minutes until yogurt is firmer. Pour remaining gelatin, very carefully, on top. Chill until firm. Cut in squares.
