Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Trim the woody ends off the asparagus spears and toss them on the baking sheet with olive oil, sea salt, and garlic powder.
Roast the asparagus for 12 to 15 minutes until the tips are slightly charred and the stalks are tender.
While the asparagus roasts, cook the bacon in a skillet over medium heat until crispy, then remove to drain and crumble.
Season the chicken breast with black pepper and sear it in the same skillet for 5 to 7 minutes per side until fully cooked, then thinly slice.
In a small saucepan, simmer the maple syrup and balsamic vinegar over low heat for 3 minutes until it reduces into a thick, glossy glaze.
Bring a pot of water to a very gentle simmer and stir in the white vinegar to help the egg whites congeal.
Crack the egg into a small bowl, create a gentle whirlpool in the water, and carefully drop the egg into the center.
Poach the egg for 3 minutes for a soft, runny yolk, then remove with a slotted spoon and pat dry.
Layer the roasted asparagus on a plate, top with sliced chicken and bacon crumbles, place the poached egg on top, and finish with a drizzle of the maple-balsamic glaze.
