Generously dredge each chicken cutlet, first in the egg mixture, then in the breadcrumb mixture, on both sides until completed coated. Lay chicken cutlets in a single layer on the cooling rack of the prepped baking sheet. Spray tops of breaded cutlets with cooking spray.
Place the baking sheet with cutlets in the oven and bake for 20-25 minutes until cooked through. (Baking time will vary based on the thickness of the chicken.)
While the chicken bakes, make your sauce: Place 1 cup of smart balance in a small saucepot, preferable one that allows you to pour easily from the sides. Melt Smart Balance over low heat, whisking often, until completely melted and no longer foamy.
Remove saucepan from heat and immediately whisk in the spice mixture you made earlier. Whisk until all ingredients blend into a smooth sauce. Set side.
Once chicken is cooked through and crust is crispy, remove from oven. Immediately sprinkle chicken with salt.
While chicken is still hot, pour some of the sauce into a clean shallow bowl. Using tongs, place a chicken cutlet in the bowl, then pour a little more sauce over the top. Turn cutlet over with tongs until completely covered with sauce, then place on a side platter. Repeat this process with remaining cutlets.
Once all cutlets are coated with sauce, you can pour more sauce over the tops of them if you desire.
Assemble sandwiches: Place a sauced cutlet on a cut brioche roll, then top with pickle chips and cheese, if desired. Serve immediately.
