Heat your oven to 425°F to get it ready for cooking.
Cut the lemons into thin rounds and arrange them on a baking sheet lightly coated with grease.
Lay the asparagus spears and chicken tenders evenly atop the lemon slices.
Drizzle olive oil over the chicken and asparagus, then sprinkle with kosher salt.
Season the chicken tenders with lemon pepper evenly for a zesty flavor.
Place the sheet pan in the oven and roast for about 15 to 20 minutes until the chicken is cooked through.
Remove from the oven and top with shaved Parmesan before serving.
Serve and enjoy your fresh, simple weeknight dinner!
