Preheat the oven to 425°F and position a rack in the top third.
Whisk together the egg and milk in a medium bowl until combined.
Place the panko crumbs in a separate shallow bowl and season the crumbs with a little salt and pepper.
Dip each chicken fillet into the egg-milk mixture, letting excess drip off, then press into the panko to coat evenly. Arrange the coated tenders on a nonstick or lined baking sheet.
Bake the chicken tenders for 15–20 minutes, or until cooked through and golden brown.
While the chicken bakes, whisk together the sriracha, honey, soy sauce, rice vinegar, and lime juice in a bowl to make the sriracha-honey glaze.
In a separate small bowl mix the sour cream, mayonnaise, Worcestershire sauce, and lime zest to make the dipping sauce; season with salt and pepper to taste.
When the tenders are done, toss or brush them with the sriracha-honey glaze to coat. Serve immediately with the lime dipping sauce on the side.
