Start by cooking ramen so it is ready when you need it. Fill a medium saucepan with water and bring to a boil. Add ramen noodles and cook 3 minutes, breaking them up with a spatula. Drain and rinse with cold water and set aside.

In a large measuring cup or bowl, combine all sauce ingredients and stir to dissolve the sugar.

Place a large heavy skillet over medium heat. Once skillet is hot, add 1 Tbsp oil, 6 cups broccoli and 2 Tbsp water. Cover with lid and sauté for 4 minutes, stirring occasionally until crisp tender. Transfer broccoli to a separate dish.

Increase to medium high heat and add 1 Tbsp oil. Add beef in a single layer and sauté 2 minutes per side or just until cooked through then reduce heat to medium low.

Re-stir the sauce if it has separated and add to the pan and simmer 3-4 minutes, stirring occasionally. It will thicken. Return broccoli to the pan along with the cooked noodles and stir or toss to combine and coat the noodles in sauce. Add 1 to 2 Tbsp water to the sauce to thin if desired. Serve garnished with sesame seeds and chives.
