Preheat oven to 400°F. Mix the softened butter with parsley, roasted garlic, all-purpose seasoning and buttery garlic pepper seasoning. Spread it over the cut sides of the French bread. Bake until the butter melts and the bread starts to crisp.
Season the pounded chicken. Dredge each piece in flour, dip in beaten eggs, then coat in panko.
Heat frying oil to 350°F. Fry the chicken until golden and cooked through, reaching 165°F in the thickest part. Drain briefly, then chop into bite-size pieces.
Warm the butter, honey, hot sauce, chili flakes and chile powder together, stirring until combined. Strain if you want a smoother hot honey.
Top the pre-baked garlic bread with mozzarella and chopped chicken. Return to the 400°F oven until the cheese melts. Drizzle with hot honey, garnish with freshly grated Parmesan and parsley, then slice and serve.
