I like to season my chicken with salt and pepper before grilling. Preheat your grill to medium-high and lightly oil the grate. Grill chicken 6-7 minutes per side until fully cooked, then let it rest a few minutes before slicing thinly.
In a large bowl, combine mixed greens, hard-boiled eggs, avocado slices, cherry tomatoes, red onion, and crumbled bacon. Toss gently so ingredients are evenly distributed.
In a small bowl, whisk olive oil, Dijon mustard, honey (or maple syrup), apple cider vinegar, salt, and pepper. Whisk until creamy and smooth.
Layer the sliced grilled chicken on top of the salad and drizzle with the Honey Dijon Dressing. Toss gently to coat, and add optional dairy-free blue cheese if desired. Serve immediately for the best flavor and texture.
