Ingredients

• 4 pieces, about 6 oz each chicken breasts
• 3 tbsp olive oil
• 2 tbsp lemon juice
• 1 tbsp, chopped fresh rosemary
• 1 tbsp, chopped fresh thyme
• 3, minced garlic cloves
• 1 tsp salt
• 1/2 tsp black pepper
• 2 medium, sliced into 1/4-inch rounds zucchini
• 1 large, cut into 1-inch strips red bell pepper
• 2 medium, sliced into 1/4-inch rounds yellow squash
• 1 small, thinly sliced red onion
• 2 tbsp, chopped fresh parsley

Instructions

1. Step 1: In a medium bowl, whisk together 3 tbsp olive oil, 2 tbsp lemon juice, 1 tbsp chopped rosemary, 1 tbsp chopped thyme, 3 minced garlic cloves, 1 tsp salt, and 1/2 tsp black pepper to create a marinade. Place 4 chicken breasts in a resealable bag and pour marinade over them, sealing and refrigerating for at least 1 hour.
2. Step 2: Preheat grill to medium-high heat (around 400°F). Remove chicken from marinade and grill for 6-7 minutes per side until internal temperature reaches 165°F and chicken is golden with grill marks; set aside to rest.
3. Step 3: While chicken grills, heat 1 tbsp olive oil in a large skillet over medium heat. Add 2 sliced zucchini, 1 large red bell pepper cut into 1-inch strips, 2 sliced yellow squash, and 1 small thinly sliced red onion. Sauté for 8-10 minutes until vegetables are tender and edges begin to caramelize.
4. Step 4: Stir in 2 tbsp fresh chopped parsley, season vegetables with salt and pepper to taste, and toss to combine. Serve the grilled chicken alongside the sautéed vegetable medley.
