To prep the cucumbers, if they are long, cut them in half, then cut the halves lengthwise. Use a small spoon, like a teaspoon, to scoop out the seeds and mushy middle. Lay the cucumbers, cut side down, and slice them into half-moons. Add them to a medium salad bowl.
Combine 3 tablespoons peanut butter, 2 tablespoons soy sauce, 2 tablespoons maple syrup, 1 tablespoon lime juice, 1 teaspoon lime zest, 2 teaspoons pressed garlic, and 1 teaspoon minced ginger in a small bowl. Mix well and add a bit of lime juice or water to thin it if needed.
Add the peanut dressing to the cucumbers and mix well.
Garnish with the remaining 1 teaspoon lime zest, ¼ cup chopped peanuts, and ¼ cup chopped cilantro.
