In a large bowl, combine the mixed greens, halved cherry tomatoes, sliced yellow bell pepper, and sliced red onion.
Top the salad with crumbled feta cheese and chopped walnuts for added texture and flavor.
In a small bowl, whisk together the olive oil, balsamic vinegar, honey, salt, and pepper to make the dressing.
Drizzle the dressing over the salad and toss gently to combine all ingredients.
Serve immediately, or refrigerate for up to 30 minutes for the flavors to meld.
Notes
Feel free to add any seasonal vegetables like roasted squash or pears for extra autumn flavors. You can also substitute the walnuts with pecans or pumpkin seeds for a different crunch.
