Ingredients
• ⅓ cup / 80 ml gluten-free soy sauce or coconut aminos
• 1 tbsp / 15 ml apple cider vinegar
• 2 cloves garlic, minced
• 1 tsp / 5 g ground ginger
• 1½ lbs / 680 g boneless top sirloin steak, cut into ½-inch-thick strips
• 8 oz / 225 g cremini mushrooms, sliced
• 1 tbsp / 15 ml avocado oil or olive oil
• 1 medium green bell pepper, seeded and cut into thin strips
• 1 medium red bell pepper, seeded and cut into thin strips
Instructions
1. Directions
2. In a large bowl, whisk together the soy sauce, apple cider vinegar, minced garlic, and ground ginger to create the marinade. Add the steak strips and sliced mushrooms, tossing well to ensure everything is evenly coated. Set aside to marinate for at least 20 minutes.
3. Heat the avocado oil in a large skillet or wok over medium-high heat. Once shimmering, add the green and red bell pepper strips. Stir-fry for 2-3 minutes until they are vibrant and crisp-tender. Use tongs to remove the peppers from the skillet and set them aside on a plate.
4. Add the steak, mushrooms, and all of the remaining marinade directly to the hot skillet. Spread into a single layer and cook for about 5 minutes, stirring occasionally, until the steak is browned and cooked through and the mushrooms are tender.
5. Return the cooked bell peppers to the skillet with the steak and mushrooms. Toss everything together for about 30 seconds to heat through. Serve immediately.

Pro Tips
• For the most tender steak, be sure to slice it against the grain.
• Don’t overcrowd the pan! If your skillet isn’t large enough, cook the steak and mushrooms in two separate batches to ensure a proper sear rather than steaming the meat.
• For maximum flavor, marinate the meat for several hours or even overnight in the refrigerator. This also cuts down on prep time the day you cook.
• Feel free to customize with other quick-cooking vegetables like broccoli florets, snap peas, or sliced onions. Add them with the bell peppers.
