Preheat oven to 400 degrees.
In a sauce pan, sauté garlic, onions and olive oil on medium heat until translucent, 5-7 minutes.
Add tomatoes, chili flakes, oregano, spinach, salt and pepper; cook for 15-20 minutes over medium-low heat until slightly reduced.
Fill four single-serve ramekins with tomato sauce until ¾ full.
Top each with two eggs and Parmesan cheese.
Bake until bubbly; egg should be slightly set yet still runny, about 10-12 minutes.
Serve with Italian bread.
