Preheat the oven to 400 degrees. Line a large sheet pan with parchment paper and set aside.
Grab three bowls. Add the flour to one bowl.
In the second bowl, combine panko, 1/2 cup freshly grated parmesan cheese, dried parsley, garlic powder, about 1/2 teaspoon each of salt and pepper. Stir.
In the final bowl, add 1-2 teaspoons lemon zest, 4-5 tablespoons lemon juice (depending on lemon flavor intensity desired), minced garlic, and 5 tablespoons melted butter. Stir.
Remove 4 tablespoons of this mixture and set aside.
Slice chicken breasts to the size of tenders (about 1- and 1/4th inch strips) or use chicken tenders.
Coat chicken in flour, heavily dredge in garlic lemon mixture, and then coat in the Parmesan panko mixture.
Place on prepared sheet pan. Use any remaining Parmesan panko mixture and sprinkle over tenders. Sprinkle lemon pepper seasoning over the tenders.
Bake in preheated oven for 10 minutes and remove.
Flip the tenders to the other side.
Place the asparagus next to the tenders and drizzle the reserved lemon butter sauce. Sprinkle remaining 1/2 cup Parmesan cheese over the asparagus and toss with tongs.
Return to the oven and bake for another 10-12 minutes or until the internal temperature of the chicken has reached 165 degrees F.
Meanwhile, whisk remaining 3 tablespoons melted butter, 3 tablespoons lemon juice, 1-2 teaspoons lemon zest, 3 tablespoons olive oil and 3 tablespoons honey in a small bowl. Add some pepper and parsley, if desired.
Remove from the oven and top with the honey lemon mixture and fresh parsley if desired and enjoy immediately.
Do not top chicken breasts with the honey lemon mixture unless eating immediately and aren't planning on having leftovers since it will make it soggy.
