Preheat the oven to 180C/350F.
Lightly spray a large baking tray then sprinkle over the breadcrumbs. Give the tray a shake so they're evenly dispersed, then spray the top. Bake in the oven for 5-8 minutes, or until the breadcrumbs are golden (please be vigilant as they'll burn quickly). Remove from the oven and place in one of the shallow dishes. Raise the oven temp to 200C/400F.
In a small pot or bowl combine 1 tsp salt and paprika, 1/2 tsp garlic powder and 1/4 tsp onion powder and black pepper.
Line up 3 large shallow dishes: the first with the flour and half of the seasoning mix, the second with 2 beaten eggs and the third with the breadcrumbs, parmesan and the rest of the seasoning. Place the baking tray at the end with an oiled wire rack on top.
Take a tender and coat it in the flour, then egg, then in the breadcrumbs and place on the wire rack. Make sure you thoroughly coat at each stage (especially the last). Repeat with all the tenders then spray them with oil. Bake in the oven for 15-20 minutes until golden and crisp and white/piping hot through the centre (smaller ones typically 15 minutes, very large ones more like 20 minutes - just be careful you don't overcook them).
Meanwhile, combine all of the garlic butter ingredients in a small bowl. You want the butter to be soft enough to brush, but not completely melted. A little creamy if you will. Pop in the microwave for 5 second blasts until you reach this consistency. Season with a pinch of salt and pepper (to taste).
Once the tenders are cooked, use a brush to dab the butter over the top side of all of the tenders. Serve with extra parmesan and parsley (measure with love). Enjoy!
