Prepare the Chicken:
Season the chicken breasts with salt and pepper.
Heat the olive oil in a grill pan or skillet over medium-high heat.
Cook the chicken breasts for 6-7 minutes on each side or until fully cooked and golden brown. Let them rest for a few minutes before slicing.
Make the Dressing:
In a small mixing bowl, whisk together the Dijon mustard, honey, and apple cider vinegar.
Gradually whisk in the olive oil until the dressing is well combined and emulsified.
Season with salt and pepper to taste.
Assemble the Salad:
In a large salad bowl, combine the mixed greens, sliced peaches, red onion, feta cheese, and toasted almonds.
Add the sliced chicken on top.
Dress the Salad:
Drizzle the honey mustard dressing over the salad.
Toss gently to combine, ensuring all ingredients are coated with the dressing.
Serve:
Divide the salad among serving plates.
Enjoy immediately while the chicken is still warm.
