  1. Marinate steak: In a large Ziploc bag, combine all steak and marinade ingredients. Seal bag and shake so meat is evenly coated. Put in the fridge to marinate for 1 hour to overnight.
  2. Bake fries: Preheat oven to 425 degrees. Spray two sheet pans generously with cooking spray. Divide potatoes between 2 pans. Drizzle 1 tablespoon olive oil over each pan. Season with salt and pepper. Toss potatoes so they get evenly coated with oil and seasoning. Lay out in a single layer on each pan. Bake for 10 minutes, then flip over and bake for 10-12 more minutes, until fries are browned and slightly crispy.
  3. While fries are baking, cook steak: Heat 1 tablespoon grapeseed or canola oil in a wok or large nonstick skillet over medium high heat. Remove steak from marinade and discard leftover marinade. Add steak to wok and cook, stirring occasionally, until browned, 5 to 8 minutes. Remove steak to a plate.
  4. Finish stir fry: Heat second tablespoon oil in the wok over medium high heat. Add onion and cook, stirring occasionally, until softened, 5 to 7 minutes. Add tomatoes and cook for 1 minute. Add beef back to the wok with tomatoes and onions. Add 1 tablespoon soy sauce, ½ tablespoon vinegar, and salt and pepper. Cook for 1 more minute.
  5. To serve: Mix fries in with stir fry. Divide cooked rice between serving plates. Top with stir fry mixture. Garnish with chopped cilantro, parsley, and green onions.
