Mix contents of the taco seasoning together until well combined. Store in an air tight jar and in a cool dry place until needed.
Place the chicken tenders, milk and taco seasoning in a bowl and mix well to combine. Leave it aside for about 1 hour (up to overnight) to marinate. This is optional, but recommended for more flavorful chicken.
Pre-heat oven to 425 F. Prepare a baking tray with parchment paper or foil and place a wire rack over it. Spray the wire rack with oil spray. Set aside.
Whisk together all the ingredients of the spiced egg wash, in a bowl. Place the panko crumbs on a plate.
To crumb the chicken tenders, use one hand for the wet coating, and the other for the dry coating. You can easily use tongs or a fork instead for the wet coating.
Place one chicken tender in the egg wash. Coat it with egg wash on both sides using one hand or tongs. Now transfer it to the plate with panko crumbs.
With your dry hand, sprinkle some of the panko crumbs over the chicken tender piece and press them down gently. Flip the tender over and sprinkle more panko crumbs and press down gently to ensure it's completely coated. Place it on the prepared tray. Repeat with the rest of the chicken tenders. Do not overcrowd the tray.
Bake in preheated oven for 7 minutes until panko crumb coating turns golden. Flip the tenders over and bake for another 7 - 8 minutes. Remove from the oven and let them cool down on the rack.
Serve with a herb and lime sour cream dip.
Mix all the ingredients together, and season with salt to taste.
