How to Make It
In a large nonstick skillet, heat the oil. Add the onion and cook over high heat until softened, about 4 minutes. Add the bacon and cook, stirring, until very lightly browned, about 2 minutes. Add the olives, jalapeños and tomato and cook, stirring, for 1 minute. Add the eggs and scramble, scraping down the sides with a rubber spatula, until just set, about 2 minutes. Add the Gruyère and stir just until melted. Season lightly with salt and pepper.
Arrange the toasted English muffins on 4 plates. Spoon the scrambled eggs on the muffins and top with the Classic Hollandaise Sauce. Garnish with the chives and serve right away.
