Spoon the sweet chili sauce into a medium-sized bowl. Juice half a lemon and stir into the chili sauce. Add the beef and stir to coat.

Heat 1 teaspoon of the olive oil in a wok over high heat. Add half the beef and stir-fry for 1 minute, until just seared. Remove to a plate. Repeat with remaining teaspoon of oil and remaining beef and remove to plate.

Add the red onion and 1 tablespoon of water to the wok, stir to release the sediment on the wok, cook for 1 minute, until the onion is tender.

Add the broccolini and snow peas to the wok, stir-fry for 1 minute. Add 2 teaspoons of water, cover the wok and wait for 30 seconds. Remove the lid, add the spinach and cooked beef, remove from heat and stir to combine.

Divide between two serving bowls. Top with cilantro and shallots. Serve with the remaining lemon cut into wedges.

TIP: You can swap the beef for pork if you prefer and it would be just as tasty!
