In a flat wok or pan, add the oil and let it heat up on medium heat
Place the block of tofu onto the heated pan, and crumble the tofu using the back of a wooden spoon. Let all the water evaporate from the tofu. This will take 10-15 minutes on high heat. Stir consistently so the tofu does not stick to the bottom of the pan.
Once the tofu is dry and crumbly, turn off the heat, pour the tofu in a bowl and set aside.
Using the same pan, add another 2-3 tbsps of sesame oil. Heat it up and add your red chillies, garlic and Thai basil. Let it sizzle until fragrant.
Add the tofu into this pan, and give it a nice stir.
Add the salt, pepper, soy sauce and sambal
Mix the tofu one last time, then turn the heat off. Keep this aside.
