For the chicken sausage: cook in a 400°F oven to an internal temperature of 160°F using a thermometer.
Warm the flatbread in the oven then melt the cheese on top.
Preheat a non-stick pan over low-medium heat with oil. Add the eggs and tomato into the pan. Move the eggs using quick circular motions with a spatula until creamy and no longer runny, (move the pan on and off the heat as needed to prevent the eggs from cooking too quickly and overcooking or drying out). Remove the pan from the heat. Season with salt and pepper to taste.
Serve the eggs over the flatbread with chicken sausage, and strawberries. Garnish with scallions.
