Preheat oven to 220˚C / 425˚F.
Place the tofu cubes in a large bowl and drizzle over 1 tablespoon of olive oil. Toss to coat. Sprinkle over the cornflour (cornstarch), furikake, smoked paprika and salt and toss again to evenly coat the tofu on all sides.
Line a tray with baking paper. Add the tofu in a single layer and bake for 18-20 minutes, until golden and a little crispy around the edges.
Meanwhile, make the Thousand Island Dressing by combining all the ingredients in a bowl; whisk until smooth. Taste to make sure it doesn’t need any extra salt.
Set out 6 glasses (you can also use small bowls) and place a handful of lettuce into each. Divide the tofu and avocado between the glasses, and add a dollop of sauce. To serve, top with a few sprigs of dill and slide in a wedge of lemon.
