Preparation

做醋：

• In a small bowl, whisk together the vinaigrette ingredients, seasoning to taste with the salt and pepper.

Make the salad:

• 将架子放置在烤箱元件6英寸处，并将肉鸡加热到高处。将面包片放在烤盘上，然后烤直到顶部酥脆，淡淡的金色，1至2分钟。翻转另一侧，直到金黄色，约1分钟。用烤面包的一侧用大蒜的切割侧面擦拭。将每个切片撒上一小块盐，放在一旁。
• Heat the oil in a 10-inch skillet over medium-high heat. When the oil is shimmering, add the mushrooms and stir to coat in the oil. Let the mushrooms cook undisturbed until the liquid they release evaporates and they’re deep golden brown, 5 to 7 minutes. Sprinkle with 1/2 tsp. salt, stir, and continue cooking, stirring occasionally, until most sides are nicely browned, 3 to 5 minutes more. Season to taste with more salt and pepper. Remove from the heat and let cool slightly.
• Toss the spinach and vinaigrette in a large bowl. Put the bread slices on four or six plates and drizzle each slice with a little olive oil. Divide the spinach among the plates, arranging it on the top of the bread but leaving part of the bread exposed. Top with the mushrooms. Using a cheese shaver or vegetable peeler, shave a few thin slivers of Parmigiano over the top. Serve immediately.
