Line a large platter with the lettuce. Arrange the cucumber and carrot on top of the lettuce, and garnish with orange (or other fruit) and cilantro. In a bowl, stir together the dressing ingredients except the peanuts (or other nuts) and drizzle over salad. Sprinkle with peanuts (or other nuts).
If you prefer a sweeter dressing, add other 1 or 2 tsp. of sugar (or stevia equivalent) or reduce the amount of lime juice.
Use the peanut dressing as a dipping sauce for vegetables or cubes of tofu (or satay), or toss it with cooked noodles.
