Prepare the pineapple. Clean and peel the pineapple, and cut it into bite-sized chunks.
Prepare the cucumber. Peel your cucumber, then cut it into half moons.
Combine and season the salad. Combine the chopped pineapple and cucumber slices in a large bowl. Add lime juice, lime zest, jalapeños, salt, pepper, and cilantro. Toss the salad to combine well. Taste for salt and pepper, and adjust as needed.
Serve. Cover and refrigerate the pineapple cucumber salad to chill for 30 minutes before serving.
Notes
Use fresh pineapple. Do not use canned pineapple.
Jalapeños are spicy. If you want less heat, you can remove the seeds. This will make them milder.
If your cucumber seems extra watery, sprinkle the slices with a little salt and let them sit for 5 minutes. The salt will draw out excess moisture. Pat the cucumber slices dry with paper towels before adding them to the salad.
