1 pound sirloin steak, sliced in thin strips
1 tsp Sri Racha sauce
2 tsp red pepper flakes
3 carrots, peeled and sliced thin
8oz whole mushrooms, sliced
1 each red, yellow, and green bell pepper, sliced
Place sliced steak in a small bowl. Add enough soy sauce to coat evenly, and add Sri Racha sauce and red pepper flakes; set aside.
Drizzle a small amount of oil in a large skillet and set over high heat. Add marinated meat to skillet and cook to desired doneness, turning only a few times to get a good sear. Remove meat and its juices from skillet into a clean bowl.
Add carrots, mushrooms, and peppers to the same skillet and cook till tender, adding more oil if needed. Return meat and juices to the pan and cook till heated through.
