Fill a container with the cornflour and add a good amount of seasoning before placing the tofu pieces inside. Secure the lid and then shake the container well so that the tofu pieces are well coated.
Meanwhile place a casserole dish onto a medium-high heat and add enough oil to fill the bottom of the pan by a few centimetres. Whilst the oil heats up, mix the sauce ingredients into a separate bowl then set-aside for now.
Carefully place the tofu into the pan and cook until crispy on all sides (around 15-20 minutes).
Meanwhile place a separate frying pan on a medium-high heat with an additional tablespoon of oil. Add the peppers and fry for 5 minutes before adding the onions. Continue cooking for a further 5 minutes before adding the garlic, pineapple chunks and remaining vegetables.
When the tofu is cooked, add to the veggies pan along with the sauce then stir through so that the sauce coats everything evenly. Serve with rice or noodles.
