This fresh and flavorful salad of Sweet-Hot Cukes and Peppers is as pleasing on the eyes as it is on the palate thanks to vibrantly hued bell peppers.
Stir together cucumbers, bell peppers, onion, serrano peppers, garlic, and kosher salt in a large bowl. Stir together vinegar, sugar, sesame seeds, mustard seeds, and celery seeds in a small bowl. Let both mixtures stand, stirring occasionally, 1 hour. Drain cucumber mixture. (Do not rinse.) Pour vinegar mixture over cucumber mixture; stir to coat. Chill 2 to 24 hours. Serve with a slotted spoon.
