Heat oil in a large ovenproof Cast Iron skillet over medium heat.
Add bacon and cook, stirring, until golden brown, about 4 minutes. Add onion and asparagus; sauté until vegetable are soft, about 3 to 5 minutes. Remove vegetables from pan and set aside.
Preheat broiler. Off heat, coat same skillet with cooking spray. Arrange bread slices tightly in bottom of skillet. In a large bowl, whisk together eggs, egg whites, milk, mustard, salt and pepper; pour over bread and allow milk mixture to soak in entirely (like when you make French toast). Sprinkle bread with 1 tablespoon of Parmesan cheese. Place skillet over medium to medium-high heat. Cook, shaking pan frequently to promote even cooking, until almost cooked through to the top, about 4 or 5 minutes.
Place skillet under broiler to set eggs, about 2 minutes. Remove skillet from broiler; top with bacon-vegetable mixture, cheddar cheese and remaining tablespoon of Parmesan cheese. Place skillet under broiler again until cheese melts, about 1 to 2 minutes. Slice into 6 pieces and serve. Yields 1 piece per serving.
