The salad is all vegetables, but there are a zillion combinations for salad ingredients to keep your options fresh and interesting. Try using different bases for the salad, such as arugula, an herb mix, raw broccoli (just dice it fine), or baby spinach. You can julienne raw zucchini and use that as your salad base. You can use no lettuce at all and just make a salad out of cherry tomatoes, red onion, jicama, and cucumbers. Adding shredded carrots to a salad is really delicious. Get creative. Or, if time is a factor and you like eating the same salad every night, develop a routine and stick with it. Either way is fine.
