Cut breasts in half horizontally to butterfly (to make fillets that are half as thick)
Spread out on parchment lined baking sheet, pat dry, and sprinkle 5 grams or about a tsp (each) of parmesan and breadcrumbs on the top of each piece- don't flip
Sprinkle all of the tops liberally with salt, pepper, garlic powder, and italian seasoning
Bake in preheated 400 degree oven for 15-20 minutes- until juices run clear and chicken isn't pink inside!
Cover with half a slice of lite provolone or mozzarella if you prefer, turn off the oven and put the chicken back in for just a minute or two to melt.
Slice french bread as thin as you can!
Lay bread on a baking sheet and spray with mist of olive oil spray, and sprinkle with garlic powder
BROIL for a minute or two until golden brown on the top. Remove.
Heat a bowl of marinara (I just use the microwave!)
Build sandwich by starting with one piece of bread, toasty side out/soft side in. Layer with 22 g (1.5 tbs) of basil aioli, then 114g chicken (that's including the half slice provolone), 1/4 cup marinara sauce, and arugula.
Top with another piece of toasted bread, soft side in and ENJOY!
