Rinse mixed salad greens under cold water and dry them. Place them in a serving bowl.

Slice strawberries and cucumber, and segment the orange. Layer these on top of the greens with sliced red onion.

In a bowl, whisk together olive oil, orange juice, lemon juice, and honey. Season with salt and pepper to taste.

Drizzle the vinaigrette over the salad and toss gently to combine.

Garnish with crumbled feta and toasted walnuts or pecans, then serve.
