Pat dry the chicken with a paper towel. Place the chicken tenderloins on a clean surface or between sheets of plastic wrap. Use the palm of your hand or a meat mallet to gently flatten them to an even ¼-inch thickness, ensuring even cooking.
Season the chicken all over with 2 teaspoons Goya All Purpose Seasoning or kosher salt and ½ teaspoon ground black pepper.
Arrange three shallow dishes. In the first, place the all-purpose flour, granulated garlic, and paprika. In the second, beat together the eggs, dijon mustard, and lemon zest. In the third, mix the seasoned panko breadcrumbs and unseasoned breadcrumbs.
Coat each tender in flour mixture, tapping off excess. Dip in the egg mixture, allowing extra to drip off. Finally, dredge in the breadcrumb mixture, pressing to adhere. Place the breaded tenders on a plate.
In a large skillet, heat enough peanut or vegetable oil over medium-high heat to reach about ¼ inch up the sides of the pan.
When the oil is hot (it should sizzle if you drop a breadcrumb into the pan). Add the tenders to the skillet in a single layer, working in batches if needed. Cook for 2-3 minutes per side or until golden brown, crispy, and cooked through (internal temperature should be 165°F or 74°C).
Transfer the chicken to a paper towel-lined plate to drain any excess oil.
Serve Chicken Tender Schnitzel hot. Garnished with lemon wedges or fresh parsley if desired.
