Heat a nonstick skillet over medium heat. Fry the ham in 1 tablespoon of the butter until slightly charred, 2 to 4 minutes per side. Wipe the skillet clean and add the remaining tablespoon butter. When the butter is melted, fry the eggs over easy, and season with some salt and pepper.
In a small bowl, toss together the baby spinach, lemon juice and some salt and pepper. Stack the ham on the bottom of the English muffin. Top with some of the dressed spinach, and then slide 1 fried egg on top. Ladle on some of the Easy Hollandaze sauce, close the muffin and serve.
Place the eggs, lemon juice, Dijon and hot sauce in a blender and blend until just combined, about 1 minute. While the blender is still running, slowly stream in the warm, melted butter through the top hole, until thickened, about 15 seconds. Adjust seasoning with more lemon juice and some salt. Hold in a thermos if necessary.
Consumption of raw or undercooked eggs, shellfish and meat may increase the risk of foodborne illness.
