Preheat the oven to 375 degrees.

Trim the crusts from the brioche and cut into 1/2-inch cubes.

Place the brioche cubes on a sheet tray and bake until golden brown, about 10 minutes, shaking halfway through.

Combine the croutons in a large bowl with the clean frisee.

Fill a wide-straight-sided saute pan with water (about two-thirds full) and add the tablespoon of sherry vinegar.

Bring to a gentle simmer over medium-high heat, adjusting the heat to maintain it.

In a dry skillet or saute pan over medium heat, brown the lardons well on all sides, about 10 minutes.

Add the minced shallots and continue to cook for 2 to 3 minutes, to soften and lightly brown them.

Without pouring off the fat, add the 1/2 cup of vinegar to the pan.

Bring to a boil, using a wooden spoon to scrape any delicious bits that have caramelized on the surface of the pan.

When the vinegar has reduced by half, about 3 minutes, turn off the flame.

Add the olive oil, salt, and pepper, and stir well to combine.

Pour this warm vinaigrette with bacon into the bowl of frisee, along with the croutons and fine herbes.

Toss well to combine.

Divide the salad among 6 serving plates, piled into small heaps.

Crack the eggs, one at a time, into a small saucer and then slide them into the simmering water.

Poach for 4 minutes, resulting in a set white and a cooked but runny yolk.

With a slotted spoon, scoop out the poached eggs, one at a time, drain, and position on top of each pile of frisee.

Sprinkle with crunchy sea salt and a few turns of a peppermill.

Serve immediately.
