In a medium bowl, mix together teriyaki sauce, scallions, ginger, garlic, and brown sugar. Add sirloin tip steak to the mixture. Let marinate for at least 30 minutes.
Cook noodles according to package directions.
Remove steak from marinade and roll ⅓ of a carrot and 2 halves of asparagus stalks into each steak slice. You can secure with toothpick if necessary (though beef may also secure to itself).
Place each wrap in a lightly oiled pan over medium heat and cook until browned on each side.
Toss peas with cooked noodles and serve beef rolls on top. Pour any extra sauce in pan over the top.
