Grilled chicken next to a pile of raw vegetables. It's the cleanest possible Monday dinner — no tricks, no sauces, just straightforward healthy eating.
Pat chicken breast dry and lightly rub with olive oil, salt, and black pepper for even seasoning.
Preheat grill or grill pan over medium-high heat for 3 minutes until hot but not smoking.
Place chicken on grill, cook 5–6 minutes per side, turning once—watch for clear grill marks and do not press down on chicken.
Check for doneness: internal temperature should reach 165°F; let chicken rest 2 minutes after grilling for juiciness.
Slice carrot, celery, bell pepper, and cucumber into sticks; arrange them raw on each plate beside the grilled chicken, serve immediately.
