1. Preheat oven to 425°F.
2. Heat 2 Tbs. oil in saucepan over medium heat. Add onion and garlic, and sauté 3 minutes, or until softened. Whisk in flour; cook 2 minutes.
3. Meanwhile, pulse tomatoes in food processor.
4. Add pulsed tomatoes and tomato paste to onions; sauté 1 minute. Whisk in broth and milk, and simmer 4 to 5 minutes, or until gravy is thickened. Season with salt and pepper, if desired. Keep warm.
5. Brush remaining 2 Tbs. oil onto ciabatta halves. Place on baking sheet, and bake 8 to 10 minutes, or until golden. Top bread with mozzarella slices, and bake 5 minutes more, or until cheese has melted.
6. Combine spinach and ¼ cup chopped basil in a bowl; divide evenly among ciabatta toasts.
7. Heat water and vinegar (1 qt. water to 2 Tbs. vinegar) in saucepan until bubbles break just before hitting the surface (160–180°F). Poach the eggs in simmering water for 4 to 6 minutes, or until whites are firm but yolks aren’t set. Remove eggs with slotted spoon and transfer to a paper-towel-lined plate. Place 2 ciabatta halves on a plate. Top each half with 1 poached egg. Repeat with remaining ingredients.
8. Stir remaining ¼ cup basil into tomato sauce. Spoon sauce over eggs.
