Preheat oven to 425 degrees. Coat baking sheet with cooking spray. Combine crushed chips with 1 T. fresh dill or 1 t. dried, and 1 T. parsley; reserve.
In small bowl, combine mayonnaise, mustard, garlic and remaining dill and parsley.
Place tilapia fillets on baking sheet. Spread tops with mayonnaise mixture, dividing evenly. Sprinkle each with 1/4 cup chip mixture to coat; pat gently to adhere. Lightly spray filets with cooking spray.
Bake 10-12 minutes or until topping is golden brown and fish is cooked through. Serve with lemon wedges.
