Iron Rich Spinach and Beef Stir Fry in 15 Min

Instructions:

1. Slice the 450g of sirloin against the grain into 5mm strips.
2. Combine 15ml cornstarch, 15ml soy sauce, and 5ml sesame oil in a bowl.
3. Toss the beef strips in the marinade until every piece is glossily coated.
4. Mince the 4 cloves of garlic, grate the ginger, and separate the green onion whites from the greens.
5. Add 30ml avocado oil to your wok over high heat until a wispy trail of smoke appears.
6. Spread the beef in a single layer and let it sit for 90 seconds until a brown crust forms before tossing.
7. Move the beef to the side; add garlic, ginger, and onion whites until the air smells intensely fragrant (about 30 seconds).
8. Dump the 280g of baby spinach on top.
9. Pour in 15ml oyster sauce and 5ml red chili flakes until the spinach is just limp but still bright green.
10. Remove from heat immediately and toss with the green onion tops. Garnish and serve.
