Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.
In a shallow bowl, whisk together the egg, a pinch of salt, and pepper. In another plate, spread the almond flour seasoned lightly with salt, pepper, and a pinch of garlic powder if desired.
Dip the chicken breast in the egg wash, then coat evenly with almond flour. Set aside for a few minutes to help the coating adhere.
Place the coated chicken breast on the baking sheet. Drizzle a little olive oil over the chicken and bake for about 18-20 minutes, or until the chicken is cooked through and the coating gets crisp.
While the chicken bakes, prepare the roasted broccoli. Toss broccoli florets with a teaspoon of olive oil, minced garlic, salt, and pepper. Spread evenly on another baking sheet and roast in the oven for 12-15 minutes until tender and slightly caramelized.
For the zesty orange sauce, combine the juice from half a medium orange with its zest, the teaspoon of ginger, and an extra minced garlic clove if desired. Warm the mixture in a small pot over low heat for 2-3 minutes to meld the flavors.
Once everything is cooked, slice the chicken and drizzle with the orange sauce, then serve alongside the roasted broccoli.
