Preheat oven to 350F. Place bacon on cooling rack set over a baking sheet or on a slotted broiler pan. Bake until crisp, about 15 minutes.
Meanwhile, heat EVOO, a turn of the pan, in a small skillet over medium-high heat. Add leeks and saut to soften, 5 minutes. Season with salt and pepper, and reserve.
Remove bacon from oven and switch on broiler. Heat a nonstick or cast-iron griddle over medium heat.
Whisk together the eggs, hot sauce, milk, some salt and pepper. Soak bread in eggs. Butter the griddle and cook bread until golden.
Arrange the cooked toast on a baking sheet. Top each with 1 slice of ham and turkey then top with some leeks, a slice of tomato, crossed strips of bacon and some cheese. Place under the broiler until cheese is melted and golden, 1-2 minutes.
Mix syrup and mustard together and serve in ramekins alongside the sandwiches.
