Preheat the oven to 400°F. Grease a baking dish with oil and set it aside.
In a large bowl, combine the lemon juice, olive oil, Dijon mustard, garlic, lemon zest, dried cilantro, onion powder, and salt. Mix well to prepare the marinade.
Add the chicken tenders to the marinade and coat them thoroughly. Cover and refrigerate for at least 30 minutes.
Transfer the marinated chicken to the prepared baking dish.
Add the chicken stock, paprika, and cornstarch to the remaining marinade. Mix well to prepare the sauce.
Pour the sauce over the chicken tenders in the baking dish and bake for 10 minutes.
Baste the chicken with the liquid in the baking dish and continue baking for another 10-12 minutes, or until the chicken is cooked through.
Garnish the chicken with fresh cilantro and serve alongside lemon wedges.
