In a large bowl, combine the lime juice, olive oil, salt, and pepper. Mix to combine the dressing.
Slice the cucumbers as thick or thin as you prefer, and place them in the large bowl with the cilantro lime dressing. I like mine pretty thin but enough to still have a crunch texture.
Add the chopped cilantro on top and toss to combine, and coat all the cucumber slices with the dressing.
Taste for seasoning and add a little more salt if needed. This also depends on the size of the cucumbers and how much lime juice your limes yield.
Serve immediately, or refrigerate the cucumber salad for 30 minutes to absorb the zestiness from the lime dressing.
Notes
*Each lime yields approximately 2 tablespoons of juice. I like to make the acid-to-oil ratio 3:1 for this, so I recommend 6 tablespoons (⅓ cup) of lime juice in total.
