1 (3 ounce) box lime or lemon Jell-O
1/4 teaspoon salt
1 cup boiling water
1 (8 3/4 ounce) can crushed pineapple
2 tablespoons lime juice
1 ripe medium avocado, peeled and halved
3 ounces cream cheese
1 cup whipped cream or prepared Dream Whip topping
1 (9-inch) crumb crust

Dissolve Jell-O and salt in boiling water.

Drain pineapple, combining the syrup with lime juice; add cold water to make 3/4 cup. Add to gelatin. Chill until very thick.

Meanwhile, dice half of the avocado. Mash the remaining half until smooth. Blend cheese into mashed avocado until creamy. Then fold cheese mixture, diced avocado, pineapple and whipped cream or prepared whipped topping into thickened gelatin. Spoon into crust. Chill until firm. Garnish with drained pineapple slices or lime slices, if desired.
