Preheat your oven to 400°F.
Prepare a shallow dish with almond flour and season lightly with salt, pepper, and any desired herbs.
Pat the chicken breast dry, then dip it first in the egg white, ensuring it is fully coated, and then dredge in the almond flour mixture until evenly covered.
Place the chicken on a parchment-lined baking sheet. Bake for 18-20 minutes, or until the chicken is cooked through and the coating is crispy.
While the chicken is baking, toss the zucchini, red bell pepper, and broccoli with 1 tsp of olive oil, salt, and pepper. Spread them on a separate baking sheet.
Roast the vegetables in the oven for about 15 minutes, stirring halfway through, until tender and lightly charred.
Once the chicken is done, remove it from the oven. Spoon a thin layer of tomato sauce over the chicken and sprinkle with Parmesan cheese. Return to the oven for an additional 2-3 minutes to warm the sauce and slightly melt the cheese.
Serve the crispy chicken alongside the roasted vegetables and enjoy your balanced, nutrient-packed meal.
