Preheat oven to 350 degrees.
Over medium heat, saute the chicken sausage and garlic until slightly browned, approximately 5 minutes.
In a large mixing bowl, combine diced cauliflower, corn, bell pepper, tomatoes, cheese, and cooked chicken sausage. In a separate bowl, combine: eggs, milk + spices. Whisk until combined.
In a greased 13 x 9 pan, lay out the bread in a single layer. Then, spread on the veggie + cheese mixture evenly over bread. Then, pour on the egg mixture. Bake for 30-35 minutes until eggs are completely baked / cooked and no longer jiggle at all. Serve hot.
