Refreshing, light, and satisfying, this cucumber salad has a good hit of lime, and is nicely grounded by the peanuts. We had it as a side dish, but it would be excellent with cold rice noodles, in a soba noodle dish, and as a garnish for rice bowls.
Peel cucumber in stripes (or leave unpeeled if preferred) and slice thinly. Place in a small serving dish/bowl.
Mix together the lime juice, sesame oil, chilli, sugar, and salt. Pour over cucumber and toss. Taste and adjust seasoning as needed. Top with chopped peanuts and serve.
