- 1 lb Beef sirloin, sliced into 1/2-inch strips

- 1/2 tsp Black pepper
- 12 oz Egg noodles

Instructions
- Step 1: Bring a large pot of salted water to a boil and cook 12 oz egg noodles according to package instructions until al dente, about 7-8 minutes; drain and set aside.
- Step 2: In a large skillet over medium heat, melt 3 tbsp butter. Add 1 medium diced yellow onion and sauté for 4 minutes until softened and translucent.
