Step 1: Season the Chicken
Season the chicken pieces with salt, black pepper, paprika, and Italian seasoning. Toss well to evenly coat all pieces.
Step 2: Cook the Chicken
Heat olive oil in a large skillet over medium-high heat. Add the chicken and cook for about 5–7 minutes until golden and fully cooked. Remove from the skillet and set aside.
Step 3: Sauté Garlic and Butter
In the same pan, reduce heat to medium and add butter. Once melted, add minced garlic and sauté for about 30 seconds until fragrant.
Step 4: Cook the Vegetables
Add zucchini, yellow squash, bell peppers, and cherry tomatoes. Cook for 5–7 minutes, stirring occasionally, until vegetables are tender but still slightly crisp.
Step 5: Add Lemon Flavor
Stir in lemon juice and lemon zest. Mix well so the vegetables absorb the fresh citrus flavor.
Step 6: Combine Everything
Return the cooked chicken to the skillet and toss everything together. Let it cook for another 2 minutes so all flavors blend.
Step 7: Finish and Serve
Sprinkle with fresh parsley and red pepper flakes if desired. Serve warm straight from the pan.
