Chicken tenders, or thin pieces of chicken breast, cook up very fast and are low in fat. They are a bit more expensive than chicken dark meat, but otherwise are perfect for bentos.
This marinated and grilled chicken really just takes minutes to prep and to cook in a grill pan. They go well in a rice-based bento, in salad, sandwiches and more.
