In a large mixing bowl, beat the eggs, season with salt, and then add the cheese.
Preheat the oven to 425 F. Coat a 9 x 12 or big oval casserole dish with oil.
Toss the potatoes with 1 tablespoon of oil, 3/4 teaspoon salt, garlic powder, and black pepper.
Bake until soft, stirring every 15 minutes, about 45 minutes to an hour.
Meanwhile, brown the turkey in a large pan over medium heat, breaking it up as it cooks. When no longer pink, add the spices and combine thoroughly.
Combine the onion, bell pepper, tomato sauce, and water. Stir, cover, and cook on low for about 20 minutes.
Spray another pan with nonstick spray, then add the eggs and 1/4 teaspoon salt, scrambling until barely set, approximately 2 to 3 minutes.
To serve, add 3/4 cup turkey and 2/3 cup eggs on each dish or bowl, then divide the potatoes and top with 1 tablespoon shredded cheese, scallions, or cilantro. Serve with salsa on the side.
