Start by washing and trimming the zucchinis. Slice them thinly into rounds or half-moons, depending on your preference. The thinner the slices, the more flavor they’ll absorb, giving you that perfect burst of freshness with every bite.

In a large bowl, combine the thinly sliced zucchini, halved cherry tomatoes, and red onion. You’ll immediately notice the contrast of colors – the bright green zucchini, the rich red tomatoes, and the deep purple of the onions. The colors alone are enough to make you excited about eating it!

In a small bowl, whisk together the olive oil, lemon juice, Dijon mustard, salt, and pepper. This simple yet flavorful dressing ties the entire salad together with its tangy and slightly sweet flavor.

Drizzle the dressing over the zucchini mixture, then toss gently to combine. Sprinkle the salad with crumbled feta cheese and fresh basil for an extra touch of flavor and color. Serve immediately or let it chill in the fridge for 20 minutes to allow the flavors to meld.
