1. Cut the chicken into small cubes, about 1 cm thick.
2. For the marinade, mix soy sauce and fish sauce with peeled and chopped garlic cloves, as well as the small chili pepper sliced into small rounds and deseeded.
3. Let the meat marinate for as long as possible, at least 30 minutes.
4. Prepare your vegetables:
5. Cut the carrots and bell peppers into small sticks, they will easily soften when cooked.
6. Slice the onions into thin strips.
7. Heat the oil in the wok, and add the onions to sauté them gently. When they start to lightly brown, add the carrots and bell peppers. Stir frequently and sauté over low heat for 15 minutes. Then set aside on a separate plate.
8. Drain the chicken a little, reserving the marinade, and sauté it in the wok. It should start to brown nicely. Season generously with pepper.
9. When the chicken starts to turn golden, add the vegetables, stir well, and gradually add the remaining marinade, making sure it doesn't stick to the bottom. Add the handful of soy sprouts.
10. Mix everything well, and regularly taste the vegetables and chicken, as some may prefer them more or less crunchy.
