First Step: Prepare Your Ingredients Begin by washing all fresh fruits and vegetables thoroughly under cold running water. Pat them dry gently with a clean towel to minimize moisture, which helps keep the salad crisp in the mason jars.

Second Step: Chop and Crumble Slice the strawberries into bite-sized pieces, chop the spring mix lettuce into manageable portions if needed, and crumble the feta cheese into small, even pieces. This preparation ensures easy layering and even distribution of flavors.

Third Step: Whisk the Dressing In a small bowl, whisk together 4 tablespoons of poppy seed dressing. If you prefer homemade, combine your favorite ingredients to create a tangy-sweet dressing. Having the dressing ready allows for efficient layering and uniform taste throughout the salad.

Fourth Step: Layer the Salad in Mason Jars Pour 2 tablespoons of poppy seed dressing at the bottom of each mason jar to prevent the lettuce from becoming soggy. Next, add ½ cup chopped strawberries, followed by ¼ cup crumbled feta cheese. Layer ¼ cup blueberries over the cheese, then gently add 1 cup of spring mix lettuce on top. This order keeps the ingredients fresh and maintains texture.

Final Step: Seal and Chill Seal the mason jars with lids or cover tightly with plastic wrap secured by rubber bands. Refrigerate for at least 30 minutes before serving to allow flavors to meld and the dressing to infuse into the layers. Before eating, shake the jar well to mix ingredients or pour into a bowl. For dietary alterations, substitute feta or dressings as needed to accommodate different preferences.
