Heat a grill or a heavy skillet over medium-high heat until hot.
In a small bowl, combine the cumin, smoked paprika, cinnamon, salt, and black pepper until evenly mixed.
Rub the chicken steaks lightly with olive oil on both sides, then press the spice blend onto the surface so it adheres.
Place the chicken on the preheated grill or skillet and cook about 5–6 minutes per side, or until the meat reaches 165°F (74°C) and the juices run clear.
While the chicken cooks, whisk together the honey, Dijon mustard, lemon juice, and minced garlic in a small bowl until smooth.
During the final 1–2 minutes of cooking, brush the honey mixture over the chicken, turning once so the glaze caramelizes without burning.
Remove the steaks from the heat and let them rest for a few minutes. Garnish with chopped parsley if desired and serve.
