Preheat your oven to 350° F.
Heat a large, seasoned cast iron skillet over medium heat. Add onions and Italian sausage, breaking the meat up into small chunks as you add it. Cook until the sausage browns, about 5 minutes. Add Mann’s Organic Broccoli and cook just until vibrant, about 3 minutes. Remove from heat.
Scramble the eggs with the egg whites lightly and season with salt and pepper if desired. Pour egg mixture into skillet, covering the contents evenly. Lay the sliced tomatoes over the top and sprinkle with goat cheese. Place skillet in oven and bake on the center rack for 25 minutes or until eggs are fully set.
