Prep: Start cooking white rice first so its ready when the stir fry is done. Cover and freeze steak 30 minutes for easier slicing.

Put ginger and garlic in measuring cup along with a tablespoon sesame oil. Microwave for 1 minute. Add remaining sauce ingredients in a bowl, stir well to dissolve the sugar, and set aside.

Place a large skillet over medium heat and add 1 Tbsp oil. Add onions and peppers over high heat and saute until browned. Remove to a plate. Add broccoli florets and sauté 4-5 minutes, partially covered with lid, stirring or tossing several times until broccoli is bright green and crisp-tender then remove to the plate of onions

Increase heat to high heat and add 1 Tbsp oil. Add beef in a single layer and sauté 2 minutes per side or just until cooked through. Quickly pull out a piece to test for doneness.

Add the sauce, reduce heat to medium/low and simmer 3-4 minutes. It will thicken. Add broccoli and stir to combine. Stir in 1-2 Tbsp water to thin the sauce if desired. Serve over white rice.
