It's popular here; most are from Mexico.

Here is a recipe I haven't tried yet. It looks interesting!
Ingredients
1 tablespoon olive oil
1 chayote squash, cut into 1/2-inch strips
1 clove garlic, minced
½ teaspoon salt, or as needed
½ teaspoon white sugar, or as needed
¼ teaspoon red pepper flakes (Optional)
ground black pepper to taste
1 tablespoon red wine vinegar
Directions
Heat olive oil in a medium skillet over medium-high heat. Cook and stir squash, garlic, salt, sugar, red pepper flakes, and black pepper in hot oil for 2 to 3 minutes.
Pour in vinegar; cook and stir until squash is slightly wilted but still firm and crunchy, 2 to 3 minutes.
