Cooking Steps

1

• Bring a large saucepan of salted water to the boil. Peel sweet potato and cut into large chunks. • Cook sweet potato in the boiling water until easily pierced with a knife, 12-15 minutes. • Drain and return to pan. Add the milk, butter and a generous pinch of salt. Mash until smooth. Season with a pinch of pepper. • Cover with a lid to keep warm.

Little cooks: Get those muscles working and help mash the potatoes!

2

• Meanwhile, cut zucchini into thin sticks. Trim green beans. Finely chop garlic.

3

• In a large frying pan, heat a drizzle of olive oil over medium-high heat. • When oil is hot, cook flank steak for 4-5 minutes each side for medium, or until cooked to your liking. • Transfer to a plate, season, cover and rest for 5 minutes.

TIP: Flank steak has long fibres running through the meat. Cutting across the grain or perpendicular to the fibres helps ensure each bite is tender and easy to chew.

4

• Meanwhile, in a medium frying pan, heat a drizzle of olive oil over high heat. • Cook zucchini and green beans, tossing, until tender, 4-5 minutes. • Reduce heat to medium-high, and add half the garlic and cook until fragrant, 1 minute. • Season to taste. Transfer to serving plates and cover to keep warm.

5

• Return frying pan to medium heat with a drizzle of olive oil. • Cook the remaining garlic, stirring, until fragrant, 1-2 minutes.
• Stir in light cooking cream and chicken-style stock powder and simmer until bubbling, 1-2 minutes. • Remove from heat, and add a drizzle of truffle oil, stirring to combine. Season with pepper.

TIP: Truffle oil has a strong flavour – add less if desired.

6

• Cut each steak in half and thinly slice each steak across the grain. • Divide flank steak and sweet potato mash between plates with garlic greens. • Spoon creamy truffe sauce over beef. Enjoy!
