Season the chicken breast evenly on both sides with sea salt, black pepper, garlic powder, and smoked paprika.
Heat the olive oil in a non-stick skillet over medium-high heat.
Add the chicken breast to the skillet and cook for 5-7 minutes per side, or until the internal temperature reaches 165°F and the outside is golden brown.
While the chicken is cooking, toast the whole-grain waffle in a toaster or oven until it is crisp and heated through.
In a small bowl, whisk together the maple syrup, Dijon mustard, and water to create a smooth glaze.
Remove the chicken from the pan and let it rest for 2 minutes before slicing into thick strips.
Place the toasted waffle on a plate, top with the sliced chicken, and drizzle the maple-dijon glaze over the top.
