Tofu cut into cubes with a side of 2 cm. Mix with soy sauce.
Whisk the egg. Continuing to beat, add flour. Heat vegetable oil in a frying pan. Dip tofu cubes in batter and fry in oil in small portions for 2 minutes. Transfer the cooked tofu to paper towels with a slotted spoon to drain excess oil.
Peel the garlic, chop. Peel carrots and peppers, cut into small cubes. Saute the vegetables in the same skillet and oil until cooked through, 4 minutes. Arrange the vegetables on a serving platter first, then the tofu.
