Sizzling chicken fajitas loaded with peppers and onions make a fresh, high protein dinner the whole family loves. Perfect for healthy eating and easily customizable for a calorie deficit or clean eats lifestyle.
Slice the chicken breasts into thin strips against the grain for tenderness.
In a large bowl, combine olive oil, lime juice, chili powder, cumin, garlic powder, smoked paprika, salt, and black pepper. Add the chicken and toss to coat evenly. Marinate chicken for at least 15 minutes.
While chicken marinates, cut red, yellow, and green bell peppers and onion into thin strips to ensure even sautéing.
Heat 1 tbsp olive oil in a large cast-iron skillet over medium-high heat until the oil is shimmering. Add the marinated chicken and cook for 4–5 minutes, stirring occasionally, until just cooked through and lightly browned. Remove chicken and keep warm.
Add remaining olive oil to the skillet. Toss in the peppers and onions and sauté at medium-high heat, stirring often, for 5–6 minutes until vegetables are crisp-tender with slight char.
Return the cooked chicken to the skillet. Toss everything together for 1–2 minutes over medium-high heat to meld the flavors.
Warm the flour tortillas in a dry skillet or microwave until soft.
Serve the sizzling chicken and vegetables immediately in tortillas. Optional: squeeze extra lime juice over the fajitas before serving.
