In a small sauce bowl, pour ½ cup of water. Add the teaspoon of the vegetable paste and whisk to dissolve. Set aside until later use.
Preheat a sauté skillet (or cast iron) to medium high heat. Coat with a tablespoon of any neutral flavored oil.
Prepare the tofu. Carefully press out the excess liquid without tearing (or breaking) the block. Slice into bite-sized cubes and pat dry. Season on each side with a sprinkle of salt & pepper.
Sear the tofu on each side until it is golden brown; just to give it color and more texture. Remove from the pan and set aside.
Using the same skillet: toss the onions, ginger, sliced green chilis, and mushrooms to sauté. Sauté for 1-2 minutes or until it is fragrant. Add the garlic and mix. Leave alone for another minute until garlic is slightly golden.
Lower down the heat to medium low. Toss the tofu back into the skillet and mix. Pour the vegetable based liquid into the skillet and stir. Add the coconut milk, stir, and cover with a lid to simmer for 3-5 minutes.
Remove the lid. Splash low sodium tamari (or low sodium soy sauce) to the broth. Season with onion and garlic powder. Stir and let it simmer, one more time, for about 5 minutes with the lid on. Turn off heat. Drizzle with a tablespoon of olive oil and a hint of lemon juice to finish. Serve with a bed of rice and garnish a whole green chili to eat.
