Toss pecans in the frothed egg white mixture first and then place in spice mixture until evenly coated. Place on sheet tray and bake for 30 minutes. The pecans should be well coated in the maple sugar.
Place chicken on a greased grill or grill pan for about 3-4 minutes on each side, or until fully cooked through. If using a grill pan, make sure to cover the chicken to ensure even cooking. Take chicken off heat, slice, and set aside until ready to eat.
While chicken cooks, whisk salad dressing ingredients together in a small mixing bowl.
Assemble all salad ingredients on a serving platter of choice. Save half of the candied pecans for snacking! Drizzle with shallot vinaigrette (1/4 cup or more, as desired) and devour!
