I still haven’t found a cactus desert pie, but I did find this tropical medley.
2 cactus pears, peeled
6 cups assorted fresh fruit (sliced kiwi, sliced carambola, whole or sliced strawberries, orange sections, banana chunks, quartered figs, cubed mango, sliced guava, and/or sliced papaya)
1/2 cup whipping cream
1 tablespoon sugar
Seems like it could be delicious. As usual, click through for the instructions.
