These are a whole new Eggs Benedict -- Hollandaise sauce is replaced with a light, kicky mustard-mayo sauce, and whole-wheat English muffins and a moderate portion of bacon can be enjoyed guilt-free. The tomatoes and kale keep the dish fresh and colorful.
Heat the oil in a large nonstick skillet. Add the Canadian bacon and shallots and cook, stirring frequently, until golden, about 4 minutes. Add the kale, remove from the heat and stir until the kale wilts, about 2 minutes. Season with pepper. Set aside and keep warm.
04Toast each English muffin in a toaster oven or under a broiler until lightly golden, about 5 minutes. Top each with a tomato slice and toast until the tomato is just slightly warm, about 1 minute. Top each muffin with the Canadian bacon-kale mixture. Crack each egg into a mug and slip into the simmering water. Cook until the whites are at desired doneness, 3 to 5 minutes. Remove with a slotted spoon and place on each Benedict. Drizzle with Hollandaise and serve.
