In a large salad bowl, combine the baby spinach, strawberries, blueberries, avocado, cucumber, and red onion.
Toss gently to mix the ingredients together.
In a small bowl or a jar with a lid, combine the olive oil, apple cider vinegar, honey, Dijon mustard, and minced garlic.
Whisk (or shake if using a jar) until the dressing is well combined and emulsified. Season with salt and pepper to taste.
Pour the dressing over the salad and toss gently to coat all the ingredients with the dressing. Sprinkle the toasted walnuts on top for a crunchy finish.
Divide the salad into four servings. Enjoy immediately as a refreshing, nutrient-packed meal.
