Method:
Preheat oven to 400°F. Arrange 8 large greased ramekins on a baking sheet; set aside.
Bring water and salt to a boil in a medium pot then whisk in grits and return to a boil. Reduce heat to medium low and simmer, stirring often, until thick and creamy, 10 to 15 minutes. Season with salt and pepper then stir in butter. Divide grits among prepared ramekins.
Meanwhile, cook bacon in a large skillet over medium heat, turning occasionally, until just crisp, 6 to 8 minutes; transfer to a paper towel-lined plate. When cool enough to handle, roughly chop bacon.
Discard all but 2 tablespoons of the bacon grease, then add greens to skillet and cook, tossing often, until wilted and just tender, about 5 minutes. Stir in bacon and season with salt and pepper. Arrange greens on top of grits in ramekins.
Crack an egg into the center of each ramekin and bake until whites are almost set, about 20 minutes. Set aside to let cool briefly then serve.
