Whisk the orange juice, soy sauce, honey, and chili garlic sauce together, then pour it over the sliced flank steak to let marinate for 30 minutes (up to 12 hours) in a bowl or Ziploc bag.
In a large skillet over high heat, add the sesame oil and veggies, and saute on high heat for 4-6 minutes, until wilted and starting to brown, then transfer the veggies to a bowl and set aside.
Place the marinated steak in the now-empty skillet over high heat, reserving the liquid for later. Cook for 5-6 minutes, until the beef develops a nice caramelized coloring, tossing every few minutes, then transfer to the bowl with the veggies.
To the empty skillet, add the rest of the marinade from the bowl or bag, and bring to a boil for 3-4 minutes. Then, turn the heat down to low, add the cornstarch and water mixture to the skillet, and stir to combine. Add the meat and veggies back to the skillet and toss.
Garnish the stir fry with sesame seeds and lime wedges, then serve over white rice, ramen noodles, or egg noodles, and enjoy!
