Thinly slice 2 firm English cucumbers and 1 sweet onion. Sprinkle cucumbers with salt, let them sit in a colander for 10 minutes, rinse, and pat dry.

In a microwave-safe bowl, soften 4 ounces of whipped cream cheese for 15-20 seconds. Add ¼ cup mayonnaise, 2 tablespoons soy sauce, 1 tablespoon rice vinegar, and 1 teaspoon sesame oil. Whisk until smooth.

Combine drained cucumbers and sliced onions in a large bowl. Toss with half the dressing and let sit for 5 minutes. Add remaining dressing and optional mix-ins.

Transfer to a serving dish, garnish with toasted sesame seeds or green onions, and serve immediately.
