2 Tbsp sugar
1 Tbsp garlic salt
1/2 Tbsp onion powder

Thinly shave partially frozen beef, using a mandoline. Add the beef marinade to shavings and let sit for 20 minutes.
Meanwhile, slice the onions and peppers with a mandoline. Sear in 3 Tbsp of oil until charred (2 minutes.) Remove and place the pan back on the burner.
Drain the beef from the marinade and cook in 3 Tbsp of oil over high heat until cooked and juices run dry.
