Cucumber Salad with Sesame Oil and Rice Vinegar

I don’t add the soy sauce (and usually skip the salt and black/white pepper, too), and for the chili oil add a dash of La-Yu oil (and sometimes the crushed red pepper as well, for some texture and a second layer of heat). Sesame seeds nice but not obligatory; it’s really the sesame oil/rice vinegar/chili marinade that does the heavy lifting. Slicing your cucumbers with a mandoline makes it 10x better, imo.
