Whisk together oil, honey, white vinegar, and Dijon mustard in a bowl until smooth; set aside.
Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a shallow bowl combine shredded coconut, panko crumbs, crushed corn flake crumbs, and a pinch of salt.
Place beaten egg whites in a separate shallow bowl.
Lightly season each chicken tenderloin with salt, dip into the egg whites, then press into the coconut-panko mixture to coat evenly.
Arrange the coated tenders on the prepared baking sheet, lightly spray the tops with olive oil spray, and bake for 25–30 minutes, turning once halfway, until cooked through.
While the chicken bakes, divide the mixed baby greens, shredded carrots, sliced tomato, and sliced cucumber among plates (about 2 cups greens per plate).
When the chicken is done, slice each tenderloin on the diagonal and place on top of the prepared salads.
Warm the vinaigrette briefly in the microwave (a few seconds) until just warm, then drizzle equally over each salad—about 1 tablespoon per serving.
