Instructions
Whisk together the ingredients for the honey mustard sauce, adding a bit of hot sauce if you like. Set aside or refrigerate until ready to serve.
Place potatoes in a pot of cold salted water. Bring to a boil on high, then reduce to medium and cook for 15 minutes.
Meanwhile, in a non-stick skillet over medium heat, caramelize the sliced onions in 1 tablespoon of olive oil with a little salt + pepper. Set aside. Save the skillet for later.
Drain and transfer the potatoes to a large mixing bowl. Add 3 tablespoons of butter and mash with a potato masher. Season with salt + pepper, to taste. Add the whisked up egg and 1/2 cup flour and combine. Fold in the corned beef and sautéed onions. (If the potatoes are very loose, mix in additional flour.)
Preheat your waffle maker. When hot, grease the surface with olive oil and add a portion of the potato mixture. Close the waffler and cook until the surface turns golden and crispy. Repeat as needed until all the mixture is cooked. Keep waffles warm on a sheet pan in a 175°F oven.
Return the skillet to medium heat with the remaining tablespoon of olive oil. When hot, add the cabbage to the skillet and season. Saute for just a minute or two. The goal is to soften the cabbage just enough, but not so much that it loses its color or wilts completely. Remove the cabbage to a plate.
Melt the remaining tablespoon of butter in the skillet over medium heat. Break 4 eggs into the skillet and cook to your desired doneness.
Create a waffle stack to serve: waffle on the bottom, then cabbage, then top with a fried egg. Drizzle some honey mustard all around the dish.
