Preheat oven to 350 degrees F. Line a 9x13" sheet pan with parchment. Coat parchment and sides of pan with cooking spray.
In a large bowl, whisk eggs, salt, garlic powder and 3/4 cup cheese until well combined. Season with pepper. Place sheet pan on oven rack and carefully pour eggs into pan. Sprinkle top with vegetables, sausage and remaining 3/4 cup cheese. Bake until eggs are set in center, 20 to 22 minutes.
Cut into 12 pieces; serve on the bread immediately, or cool completely, wrap individually and freeze for up to 2 weeks. Thaw in refrigerator before reheating in microwave or toaster oven.
Tip: Customize each area of the sheet pan with different toppings before baking. To please meat eaters, add diced ham or cooked bacon instead of the plant-based sausage.
