Whisk together vinegar, oil, salt and pepper. Stir in basil.
Mix in chicken tenders and allow to marinate for at least a half hour.
Thread chicken tenders onto skewers (optional)
Cook chicken on a grill, griddle or skillet.
Notes
I like the flavor of aged balsamic vinegar, but you can experiment with other vinegars. You may want to start by using 1/2 teaspoon of the vinegar and tasting the marinade before deciding to add the other 1/2 teaspoon. Consider serving chicken with grilled asparagus and pineapple.Grilled Chicken Tenders with Basil Served with Grilled Asparagus and Grilled Pineapple
