Step 1: Prepare the greens. Gently wash and thoroughly dry your mixed greens. Place them in a large salad bowl.
Step 2: Prepare the fruit and avocado. Wash the berries and pat them dry. Slice the strawberries. Dice the avocado. Add the sliced strawberries, blueberries, raspberries, and diced avocado to the bowl with the greens. If using, add the thinly sliced red onion.
Step 3: Toast the nuts (optional). In a dry skillet over medium-low heat, lightly toast the pecans or walnuts for 3-5 minutes until fragrant, stirring occasionally. Be careful not to burn them. Let them cool slightly. Add them to the salad bowl.
Step 4: Make the vinaigrette. In a small bowl or jar with a lid, combine the extra virgin olive oil, fresh lime juice, honey, and Dijon mustard. Whisk vigorously or shake well until emulsified. Season with salt and freshly ground black pepper to taste.
Step 5: Dress and serve. Just before serving, pour the desired amount of vinaigrette over the salad. Gently toss to combine all ingredients, ensuring everything is lightly coated. Serve immediately and enjoy this delightful addition to your collection of salad recipes!
