Preheat the oven to 375-degrees.
In a large bowl combine the potato slices along with the olive oil, lemon pepper seasoning, and sage. Toss until the potatoes are well coated and arrange the slices on a baking sheet and bake for 20 minutes or until the potatoes are golden and slightly crisp around the edges. Remove from the oven and set aside.
While the potatoes are roasting, prepare the turkey by heating a grill or a grill pan to medium-high heat. While the grill is preheating slice the turkey breast into½-inch pieces and season with olive oil, poultry seasoning, and sea salt.
When the grill is ready place the turkey on the grill on each side for about 4 minutes, the turkey should still look moist and juicy with nice grill marks. If you have an instant-read thermometer the temperature should be 155-degrees, the meat will carry over cook to 165-degrees. Set aside until ready to use.
To make the vinaigrette, combine the maple syrup, mustard, vinegar, and cayenne together in a bowl. While whisking slowly drizzle in the oil until all of it has been incorporated. This dressing can be made up to 3 days in advance for the best quality.
You are now ready to build your salad. To get started, arrange 1 cup of baby spinach on each plate. Arrange ½ cup of sliced potatoes on and around the salad, followed by half an orange that has been sliced, a few pieces of red onion, 2 tablespoons of almonds, and 1 tablespoon of dried cranberries. Pair the salad with maple mustard vinaigrette. Serve immediately.
