3 env. Knox unflavored gelatin
1/4 c. sugar
2 c. orange juice, heated to boiling
2 1/2 c. plain yogurt
1 c. mandarin oranges, drained (reserve syrup)
Use any combination to equal 2 cups: sliced bananas, sliced strawberries, chopped apples, chopped walnuts, raisins, blueberries, dried fruits

In a large bowl, mix unflavored gelatin with sugar. Add hot juice and stir until gelatin is dissolved. With wire whip or rotary beater, blend in yogurt and reserved syrup. Chill, stirring occasionally, until mixture resembles consistency of unbeaten egg whites. Stir in oranges and fruit and nuts. Pour into 13 x 9 inch pan. Chill until firm. To serve, cut into squares.
