Place half of bread slices in bottom of a 13 x 9-inch baking dish coated with cooking spray. Spread spinach mixture over bread. Top with tomato slices; sprinkle evenly with feta and half of Asiago cheese. Arrange remaining bread slices over cheese. Combine 1/4 teaspoon salt, 1/4 teaspoon pepper, milk, and remaining ingredients, stirring well with a whisk. Pour over bread; sprinkle with remaining Asiago cheese.
