Once the cauliflower and veggies begin to brown, heat coconut oil on medium-high in another pan, remove tofu from paper towel and cut into 1 inch cubes. Fry up the tofu, flipping often to brown each side. While tofu cooks, prepare your sauce and set aside until the tofu is browned and crispy on all sides. Once tofu is crispy, add sauce and turn off heat. Stir to coat all sides.
