Method 

  • Toss steak strips with 1 tbsp cornstarch until coated. Heat avocado oil in a skillet over medium heat. Sear the meat in two batches to avoid overcrowding. Remove and place in the slow cooker.
  • Reduce heat to low. Add garlic and ginger to the skillet and stir for 30 seconds. Add Bloody Mary mix, soy sauce, oyster sauce, brown sugar, and black pepper. Scrape up any browned bits for flavor.
  • Pour the sauce over the steak in the slow cooker. Cover and cook on low for 4 hours.
  • Add sliced bell peppers and onion. Cook for another 45 minutes.
  • Mix 1 ½ tbsp cornstarch with 3 tbsp water to make a slurry. Stir into the slow cooker and cook for 15 minutes to thicken. Serve hot over rice, noodles, or mashed potatoes with sesame seeds and sliced green onions.
