each egg bakes in its own ramekin, scale up ingredients to fit
Preheat oven to 325°F.
Heat a tablespoon of olive oil or butter (or some of each) and cook the vegetables you'd like for 5 or 10 minutes, until softened. Set aside to cool slightly.
Lightly butter the inside of each ramekin. Add a tablespoon or two of cooked vegetables to the bottom of each ramekin. Crack in an egg, add salt and pepper, top with a tablespoon of cream each, and a dot of butter.
Place ramekins in a baking pan, fill pan halfway with boiling water, then bake for 15–20 minutes, until egg is set. Remove ramekins from the water bath and serve right away.
