Heat olive oil in a large heavy oven-safe skillet over medium-high heat. Add in onion, zucchini, and bell peppers. Saute until vegetables are tender, about 5-7 minutes.
Add in garlic and paprika and saute one minute.
Pour in diced tomatoes and stir in salt. Bring to a simmer and reduce heat to medium-low. Simmer 15 minutes. Preheat oven to 375 degrees while you wait.
Create 6 little nests in the tomato mixture to hold the eggs. Crack eggs directly into the holes.
Transfer skillet to the preheated oven and let cook until egg whites are set, about 8 to 10 minutes.
Serve hot with bread.
Notes
Options:Instead of baking the eggs directly in the vegetable mixture, you can fry the eggs individually to go with the meal or skip the eggs and baking all together for more of a ratatouille version.Add slices of manchego cheese to the top of the dish before putting it in the oven for Pisto Manchego, a regional version of the dish.
