Preheat the oven to 400°. In a small skillet heat the olive oil and add the garlic and onions. Cook over medium heat until the onions begin to soften. Add the tomatoes and peppers, season with salt and pepper, and cook for another minute or so (just long enough to have the flavors combine but not overcook as they'll finish cooking in the oven).

Grease the ramekins with a bit of the butter and add equal amounts of the tomato and pepper mixture into each. Make a small indentation in the middle and crack one egg into each indentation. Place in a shallow baking pan and bake in the middle of the oven for about 10-15 minutes, depending on how "set" you like your eggs. (For more than 2 servings, cook for 15-20 minutes.) If you have extra tomato mixture, add a bit on top, garnish with a sprig of cilantro and sprinkle with a bit more ground pepper, and enjoy!
