Cut the pressed tofu into equal bite-size cubes.
Mix 1 ½ tablespoons of soy sauce with 1 ½ teaspoons of gochujang in a shallow bowl. Place tofu to marinate for 30 minutes, turning the pieces halfway through.
Wash soybean sprouts and simmer them in salted water over medium-high heat for 20 minutes. Drain and set aside.
Chop the blanched spinach roughly and add half a teaspoon garlic, ½ teaspoon salt, 1 teaspoon sesame oil, and 1 teaspoon sesame seeds. Set aside.
Pan-fry the tofu in some neutral oil on a non-stick pan on medium-high heat. Let the tofu brown on all sides.
Wipe the pan clean and heat some more oil until hot. Fry the mushrooms until nicely browned. Season with salt only after frying.
Optional step: individually sauté the shredded carrot and bell pepper just until lightly soft. You can also leave them raw.
Prepare the dressing by whisking all the ingredients together in a small bowl.
Place 1 cup of rice in each of the 3 bowls and top with equal amounts of veggies and cooked tofu. Sprinkle with optional sesame seeds and gim, and drizzle the Gochujang dressing to serve. Dig in!
