In a small sauté pan, cook shallots over medium high heat until soft and slightly golden; set aside.
Whisk together milk, flour and eggs in separate mixing bowl. Add shallots, spinach, tomatoes and bacon; combine. Fold in cheese and salt and pepper to taste.
Spray a pie pan with cooking spray and fill with egg mixture.
Bake for 50-55 minutes. Serve immediately and enjoy!
