Add the bacon slices to a food processor and pulse until it is in crumbles. It may stick together and be paste-like, which is fine because it will stick to the eggs better! Remove the bacon and place it in a bowl. Do NOT clean out the food processor! Add the egg yolks, mayo, yogurt, mustard, salt, pepper, and roasted garlic cloves (squeeze them out of the bulb) to the food processor. Add in a drizzle of reserved bacon grease if you have it, like 1 to 2 teaspoons. Blend until smooth and creamy and mousse-like. Scoop out the mixture and spoon it (or pipe it with a pastry bag) into the open egg whites. Top the yolk mixture with a sprinkle of the crumbled bacon, pressing it gently to adhere. Add some blue cheese crumbs. Slice the asparagus in half if needed (you'll need to cut it to get 18 pieces and I recommend doing it AFTER cooking) and stick it down in the eggs. Sprinkle on smoked paprika! Sprinkle on chives! Serve it. Eat it. Done.
