Feel free to get creative with this salad! If you're looking for a twist, avocado slices add a lovely creaminess, and feta can bring in a salty kick that pairs beautifully with the harissa. If you don’t have harissa paste on hand, a mixture of paprika and cayenne pepper with some olive oil can also work in its place. This salad keeps well in the fridge for up to two days; however, it's best enjoyed fresh. If you plan to store leftovers, I recommend keeping the dressing separate to maintain the crisp texture of the vegetables. Enjoy your culinary adventure!
