Preheat your oven to 400°F (200°C). Peel and dice the sweet potato into 1/2-inch cubes.
Toss the sweet potato cubes with 2 tablespoons of olive oil, a pinch of salt, and black pepper. Spread them in a single layer on a baking sheet.
Roast the sweet potatoes in the oven for about 25-30 minutes or until tender and slightly crispy on the edges, stirring halfway through.
While the sweet potatoes roast, thinly slice or shred the chicken breast. In a non-stick skillet, warm the remaining 1 tablespoon of olive oil over medium heat.
Add the chicken to the skillet and lightly sauté until it is heated through and just starting to brown, about 2-3 minutes.
Add the fresh spinach to the skillet and stir until just wilted, about 1 minute.
Crack the eggs directly into the skillet, season with a pinch of salt and black pepper, and gently scramble them with the chicken and spinach until fully cooked.
Once the eggs are cooked and the sweet potatoes are roasted to perfection, plate the scramble alongside a generous serving of sweet potatoes. Enjoy your balanced breakfast!
