2 (3 oz) boxes strawberry Jello
2 cups boiling water
2 (10 oz) pkg frozen strawberries
2 large bananas
1 cup strawberry or banana yogurt

Dissolve Jello in 2 cups boiling water. Add frozen strawberries, stirring occasionally until thawed. Add finely diced bananas.

Pour half of the strawberry mixture into an 8x8x2-inch pan; chill. Spread evenly with yogurt. Pour remaining strawberry mixture on top of the yogurt.

Refrigerate until set. Cut into 9 squares. Top with whipped cream or more yogurt, if desired.
