Here is Martha's recipe for Sesame Beef. This meal only takes about 30 min and you'll definitely love it. I used twice as much meat in my recipe to make sure we had plenty of leftovers so my sauce wasn't as thick, despite the fact that I added extra cornstarch. Regardless, it was a good meal!
2 tbsp soy sauce
2 tbsp dry sherry (vinegar)
1 tbsp sugar
2 tsp rice vinegar
1/2 tsp red pepper flakes
1/2 tsp cornstarch
1 tbsp + 1 tsp veg oil
3/4 lb New York Strip steak, thinly sliced (I used flank steak to save time on slicing)
2 red bell peppers, thinly sliced
2 garlic gloves, minced
1 tbsp sesame seeds
cooked rice for serving
thinly sliced scallions
**I added grilled pineapple and mushrooms**
1. In a small bowl, combine soy sauce, sherry, sugar, vinegar, red pepper flakes and cornstarch. In a large skillet, heat 1 tbsp oil and cook the meat over med-high heat, until one side is browned, about 2 min. Transfer to plate.
2. Add 1 tsp oil to the skillet and add peppers (and mushrooms). Cook for 2 min until peppers are crisp and tender. Add garlic and cook until fragrant, 30 seconds. In a separate skillet add a little bit of oil and cook pineapple until browned on the edges.
3. Whisk soy sauce mixture into skillet, along with steak. Cook, stirring until sauce thickens and add sesame seeds. Spoon beef mixture over white rice and top with scallions (and pineapple).
