Preheat your oven to 400°F.
Begin by scoring the pork belly skin lightly with a sharp knife. Season with salt, pepper, and any desired herbs.
Place the pork belly in a slow cooker with a splash of broth or water. Slow-braise on low heat for 2-3 hours until the meat is tender.
Once tender, increase the heat in your oven or use a broiler to crisp the skin for 5-8 minutes, watching carefully to avoid burning.
While the pork belly crisps, prepare the vegetables: toss your chosen Brussels sprouts and carrots (or pre-mixed vegetables) with a tiny drizzle of olive oil, salt, and pepper, then roast in the preheated oven for about 15-20 minutes until lightly caramelized.
Heat the cooked lentils gently on the stovetop if needed.
For an extra protein kick, quickly whisk and lightly poach one egg white in simmering water for 1-2 minutes, ensuring it remains tender.
Plate the crispy pork belly, add a serving of warm lentils, top with the poached egg white, and finish with a side of the mixed roasted vegetables.
Serve immediately and enjoy your balanced, flavorful dinner.
