Preheat your oven to 400°F (200°C).

If using individual ramekins, divide the cherry tomatoes, red bell pepper, red onion, garlic, and feta cheese evenly among four dishes. For a large baking dish, combine all ingredients and place the feta in the center. Drizzle with olive oil.

Mix the dried oregano, sea salt, dried thyme, black pepper, and red pepper flakes in a bowl. Sprinkle this over the feta and vegetables.

Place your ramekins or large dish on a baking sheet and bake for 25 minutes, until the tomatoes are blistered and the feta is golden on top.

Carefully stir the mixture and fold in the fresh baby spinach.

Create small wells in the mixture for the eggs and crack them into each well.

Return to the oven for an additional 10 minutes, until the egg whites are set.

Remove from the oven, let cool slightly and sprinkle with optional herbs or chives before serving.
