Preheat your oven to 400°F (200°C). Peel (if desired) and cut the sweet potato into 1/2-inch cubes. Toss with 1 teaspoon olive oil, salt, and pepper, and spread evenly on a baking sheet.
Roast the sweet potatoes in the oven for about 20-25 minutes, until tender and slightly crispy on the edges, stirring halfway through for even cooking.
While the sweet potatoes roast, dice the chicken breast into small bite-sized pieces. In a non-stick pan, heat the remaining 1 teaspoon of olive oil over medium heat.
Add the diced chicken to the pan and cook until lightly browned and heated through, about 4-5 minutes.
Add the fresh spinach to the chicken and cook until it wilts, stirring occasionally.
Crack the eggs into a bowl, season with salt and pepper, and whisk until well combined. Pour the eggs over the chicken and spinach mixture.
Gently stir the eggs with the chicken and spinach, allowing them to scramble and cook until just set, about 2-3 minutes.
Plate the chicken and spinach egg scramble alongside the roasted sweet potatoes and serve immediately.
