In a small, wide bowl melt the butter and stir in the key lime juice.
In a separate small, wide bowl, mix together panko, breadcrumbs, grated parmesan, garlic powder, salt, pepper, parsley, oregano, and onion powder.
Cut boneless, skinless chicken breasts in thirds or fourths.
Dip the chicken into the butter and key lime juice mixture.
Coat the chicken tenders in the breadcrumb mixture.
Optional: use a thin, metal spatula/turner to flip the chicken tenders (making sure to scrape up the coating along with the chicken) halfway through cooking to help brown both sides.
