Preheat your oven to 400°F.
Peel and dice the sweet potato into small, even cubes. Toss with a little olive oil, salt, and pepper, and spread on a baking sheet.
Roast the sweet potato cubes in the oven for about 20-25 minutes, or until tender and lightly caramelized.
While the sweet potato roasts, heat 1 teaspoon of olive oil in a skillet over medium-high heat. Add the lean ground beef, breaking it up with a spatula as it cooks.
Sprinkle in the cumin, paprika, salt, and pepper. Continue cooking until the beef is browned and cooked through.
Add diced red bell pepper to the skillet and sauté for an additional 2-3 minutes until it softens slightly.
In a separate small non-stick pan, cook the egg to your preferred style (fried or poached works well) to top the hash bowl.
Meanwhile, lightly wilt the spinach either in the skillet with the beef or in a separate pan.
Assemble your bowl by layering the roasted sweet potatoes, spiced ground beef and red bell pepper mixture, and wilted spinach. Top with the cooked egg.
Finish with an extra sprinkle of salt and pepper if desired, and serve warm.
