Wash and dry your produce. Chop romaine into bite-sized pieces, slice cucumbers, dice tomatoes, and cube avocado.

In a large bowl, combine chopped romaine, sliced cucumbers, diced tomatoes, and avocado cubes. Sprinkle sunflower seeds on top and toss gently.

In a separate bowl, combine fresh herbs and minced garlic. Add Greek yogurt and lemon juice, whisk until smooth.

Pour the dressing over the salad ingredients and toss well to coat everything evenly.

Serve immediately or store dressing separately for later use.
