Wash and dry mixed greens thoroughly and place in a large salad bowl.
Toast the almonds in a dry skillet over medium heat for 3-5 minutes until golden and fragrant. Set aside to cool.
Gently toss the mixed greens, diced strawberries, blueberries, and cooled toasted almonds in your salad bowl.
Arrange the sliced hard-boiled eggs around the edge of the bowl.
Sprinkle the crumbled feta cheese evenly across the top.
If using optional ingredients, add sliced avocado, sprinkle with granola or chia seeds, or dollop Greek yogurt on the side.
Drizzle with your favorite dressing, keeping it light to allow the fresh flavors to shine through.
Season with salt and freshly ground black pepper to taste.
For a touch of sweetness, drizzle with a small amount of honey or maple syrup if desired.
Serve immediately while the greens are crisp and the ingredients are at their freshest.
