Preheat oven to 350°F. Spray a 7x11 or 9x9 glass baking dish with cooking oil and set aside.
In a large skillet over medium heat, add onions and sauté until translucent, about 3-4 minutes. Add in bell peppers and sauté for another 5 minutes, then add in minced garlic and sauté for 1 minute more. Remove from heat and pour onion and pepper mixture into glass baking dish.
In a medium mixing bowl, combine eggs and milk and whisk until eggs are beaten. Add in grated zucchini and carrot shred and stir until everything has been mixed in.
Pour egg mixture into glass baking dish, making sure that everything is spread out evenly.
Transfer to oven and bake for 35-45 minutes or until eggs are firm and cooked through.
Remove and let cool for 5 or so minutes before cutting and serving.
