In a skillet on medium-high heat, saute the bacon for 5 minutes, stirring often, until brown and crispy. Drain the bacon on paper towel and set aside. Remove the excess bacon fat from the pan. Add the blanched cauliflower and butter and cook stirring often, to coat them with the butter for 5 minutes, or until golden brown. Add the honey and 1 tablespoon red wine vinegar. Season with salt and pepper. Let the cauliflower brown, about 5 more minutes. Remove from heat and set aside. Meanwhile, in a bowl mix the arugula, shallots, remaining red wine vinegar, and olive oil. Season the salad with salt, and pepper, to taste. When ready to serve, mix the arugula salad with the cauliflower and garnish with pine nuts.
