Slice the chicken breasts into thin strips. Wash and prepare the broccoli, carrots, and bell peppers.
Heat the olive oil in a large skillet or frying pan over medium-high heat.
Add the sliced chicken to the pan. Season with salt and black pepper. Cook for 5–6 minutes, stirring occasionally, until the chicken is fully cooked and lightly golden.
Add the minced garlic and cook for about 30 seconds until fragrant.
Add the broccoli florets, sliced carrots, and bell peppers to the pan. Stir everything together.
Cook the vegetables for 4–5 minutes, stirring frequently, until they are tender but still slightly crisp.
Pour in the soy sauce and lemon juice. Stir well so the chicken and vegetables are evenly coated.
Cook for 1 more minute, then remove the pan from the heat.
Serve the chicken veggie bowl immediately while warm and enjoy.
