In a bowl, combine the lemon juice, soy sauce, basil, oil, vinegar, and lemon zest. Lay the tofu slices in a baking dish that can hold them in a single snug layer. Pour the marinade over the tofu. Bake for 30 minutes, or until the tofu is nearly dry and well browned.
To make the broccoli rabe, chop the tender stalks and greens into 2-inch pieces and soak them in a large basin of cold water.
In a heavy, wide saute pan over medium heat, warm the oil. Add the garlic and saute gently for 3 to 5 minutes, until golden. Add the red pepper flakes and tofu and saute for 1 minute. Scoop the greens from the water and add them to the pan. Raise the heat and turn the greens over in the oil with a pair of tongs. When the greens begin to simmer, reduce the heat to low and cover. Cook for 10 to 15 minutes, until the greens are tender.
Season with salt and pepper and serve drizzled with some of the liquor and garnished with the lemon wedges and garlic cloves.
