👨🍳 Instructions
Sauté sliced flank steak in olive oil over high heat until browned, then remove from the pan.
Stir-fry broccoli florets and carrots in the same skillet for 5 minutes until tender-crisp.
Return the beef to the skillet, add the low-sodium stir-fry sauce, and toss until heated through.
Toss the cooked brown rice with a splash of sesame oil to keep grains separate, then divide across four bento containers.
Top each brown rice bed with the savory beef stir-fry vegetables and lean beef strips.
Allow all containers to cool completely before securing lids and storing in the refrigerator.
