With a Y vegetable peeler, slice the cucumber into ribbons. If You don't have a Y peeler, you can use a spiralizer or whatever tool you've got to make veggies into noodles. Toss the cucumber ribbons and fresno peppers in a bowl with a pinch of salt and a sprinkling of sesame seeds.
Put all the ingredients for the sesame dressing in a small bowl and whisk to combine. Lightly dress the salad and top with parsley or cilantro and more sesame seeds.
