Heat a large, deep 10–12 inch skillet (oven-safe if possible) over medium heat. Add the olive oil. When it shimmers, add the diced onion and bell pepper. Cook for 5–7 minutes, stirring occasionally, until the onion is translucent and the pepper softens slightly.
2 tablespoons olive oil, 1 medium yellow onion, 1 red bell pepper
Stir in the chopped zucchini and cook for 3–4 minutes, until it begins to soften and pick up a little color. Add the minced garlic and cook for 30–60 seconds, just until fragrant, stirring constantly so it doesn’t burn.
1 small zucchini, 3 cloves garlic
Sprinkle in the ground cumin, smoked paprika, red pepper flakes, salt, and black pepper. Stir well to coat the vegetables in the spices and let them toast for about 1 minute to deepen their flavor.
1 teaspoon ground cumin, 1 teaspoon smoked paprika, 1/4-1/2 teaspoon red pepper flakes, 1 teaspoon salt, 1/2 teaspoon black pepper
Pour in the crushed or diced tomatoes and the water or vegetable broth. Stir, scraping up any browned bits from the bottom of the pan. Bring to a gentle simmer, then reduce heat to medium-low and cook for 8–10 minutes, stirring occasionally, until the sauce thickens slightly. It should be saucy but not watery.
1 can (14.5-ounce) crushed or diced tomatoes, 1/4 cup water or low-sodium vegetable broth
Stir in the spinach and cook for 1–2 minutes, just until wilted. Taste the sauce and adjust seasoning with more salt, pepper, or red pepper flakes if needed. If it tastes flat, add a small pinch of salt or a squeeze of lemon juice if you have it.
2 cups fresh baby spinach, 1 teaspoon salt, 1/2 teaspoon black pepper, 1/4-1/2 teaspoon red pepper flakes
For an even more filling vegetarian dinner, stir in a handful of cooked chickpeas or white beans and warm them through for 1–2 minutes.

Using the back of a spoon, make 6–8 small wells in the sauce. Crack one egg into each well, trying to keep the yolks intact. If a yolk breaks, leave it—it will just help enrich the sauce.
6-8 large eggs
Sprinkle the crumbled feta evenly over the skillet, focusing it around the eggs. Scatter the shredded mozzarella or Monterey Jack over the top for a melty, cheesy finish.

For the stovetop method, cover the skillet with a lid and keep the heat on low. Cook gently for 8–12 minutes, checking starting at 8 minutes. The whites should be set and the yolks still a bit soft if you like them runny. For firmer yolks, cook a few minutes longer.
For the oven method, preheat the oven to 375°F (190°C) while the sauce is simmering. After adding the eggs and cheese, transfer the oven-safe skillet to the oven and bake for 8–12 minutes, until the egg whites are just set to your liking. Give the pan a gentle shake; if the whites are still very jiggly, continue baking a bit longer.
Once the eggs are cooked to your preference, remove the skillet from the heat. Let it rest for 3–5 minutes so the sauce can thicken slightly. Sprinkle with chopped fresh parsley or cilantro and add a final crack of black pepper or pinch of red pepper flakes if desired.
2 tablespoons fresh parsley or cilantro, 1/2 teaspoon black pepper, 1/4-1/2 teaspoon red pepper flakes
Spoon a generous portion of vegetables and 1–2 eggs into shallow bowls. Serve hot with crusty bread, warm tortillas, rice, or a simple side salad. Set the skillet on a trivet in the center of the table for a cozy, family-style dinner.
