Preheat oven to 400 degrees F.

If using ramekins or individual serving dishes, divide the tomatoes, bell pepper, red onion, garlic, and feta cheese between 4 oven-safe dishes. Drizzle a tablespoon of olive oil over each dish.

If using one large dish, combine the tomatoes, bell pepper, red onion, and garlic in the dish and place the feta in the center. Drizzle the olive oil over the feta and veggies.

Place the dried oregano, salt, dried thyme, black pepper, and red pepper flakes in a small bowl. Stir to combine.

Sprinkle the spice mixture over the feta and veggies, dividing equally if using individual servings.

Place ramekins on a baking sheet or place the baking dish directly in the oven. Bake for 25 minutes.

Remove the dishes from the oven and stir to combine so the feta is evenly mixed with the veggies. Then add the spinach and stir until combined.

Create a well in the middle of each ramekin or four wells if using one baking dish. Crack the eggs into the wells.

Place dishes back in the oven and bake for an additional 10 minutes.

Top with optional chopped fresh herbs or sliced chives.

Serve with crusty baguette, toast, or pita for dipping.
