1 (20 ounce) can pineapple tidbits, well drained
1 (11 ounce) can mandarin oranges, well drained
1 1/2 cups miniature marshmallows
1 can (1 cup) flaked coconut

In large bowl, combine sweetened condensed milk, yogurt, lime juice and rind; mix well. Stir in remaining ingredients. Chill until mixture starts to thicken.
