Slice the chicken breasts into thin strips if not already sliced. Season the chicken with paprika, black pepper, and salt. Mix well to coat evenly.
Heat the olive oil in a large skillet or frying pan over medium-high heat.
Add the seasoned chicken to the pan. Cook for 5–6 minutes, stirring occasionally, until the chicken is fully cooked and lightly golden.
Add the minced garlic to the pan. Stir and cook for about 30 seconds until fragrant.
Add the broccoli florets, sliced bell pepper, and sliced carrot. Stir everything together and cook for 4–5 minutes until the vegetables are tender-crisp.
Pour in the low-sodium soy sauce and lemon juice. Stir well to coat the chicken and vegetables evenly.
Cook for another 1–2 minutes, stirring occasionally, until everything is heated through and the sauce is lightly absorbed.
