Preheat your oven to 375°F.
Score the pork belly lightly and season with salt, pepper, and your favorite herbs. Place it in a small Dutch oven with a splash of water or broth.
Cover and slow-braise the pork belly in the oven for about 1.5 to 2 hours until tender.
While the pork is braising, drain and rinse chickpeas, then toss them with a little olive oil, salt, and pepper. Spread them on a baking sheet.
Cut the Brussels sprouts and carrots into bite-sized pieces, toss with olive oil, salt, and pepper, and combine with the chickpeas on the baking sheet.
Roast the chickpeas and vegetables in the oven for 20-25 minutes, stirring halfway through, until they are crispy on the edges.
Meanwhile, gently whisk the egg whites and cook them in a non-stick pan over medium-low heat until just set, forming a light, airy scramble.
Once the pork belly is tender, remove it from the braising liquid. Optionally, crisp the surface by broiling for an additional 3-5 minutes if desired.
Plate a serving with slices of pork belly, a portion of the roasted chickpeas and vegetables, and the egg white scramble.
Enjoy the medley of textures and flavors in this protein-rich, balanced dinner.
