Instructions

Roast the Potatoes
1

Preheat your oven to 220°C/200°C fan/gas mark 7.

Chop the potatoes into 2cm chunks (no need to peel).

Pop the chunks onto a large baking tray. Drizzle with oil, season with salt and pepper, then toss to coat. Spread out in a single layer. TIP: Use two baking trays if necessary.

When the oven is hot, roast on the top shelf until golden, 25-35 mins. Turn halfway through.

Seasoning Time
2

Meanwhile, halve and peel the red onion, then cut each half into roughly 3cm wedges.

Trim the root and dark green leafy part from the leek and discard. Halve lengthways, then thinly slice.

Peel and grate the garlic (or use a garlic press).

Fry the Chicken
3

Heat a drizzle of oil in a large frying pan on medium-high heat.

Once hot, lay the chicken thighs flat in the pan. Sprinkle over the lemon & herb seasoning.

Fry until browned all over, 3-4 mins each side. IMPORTANT: Wash your hands and equipment after handling raw chicken and its packaging.

Ready, Steady, Bake
4

When the chicken is browned all over, add in the garlic and fry until fragrant, 30 secs more. Then, transfer the chicken to another baking tray. 

Pop the onion wedges alongside the chicken. Drizzle with oil, season with salt and pepper, then toss to coat.

Bake the chicken and onion on the middle shelf of your oven until cooked through, 12-15 mins. IMPORTANT: The chicken is cooked when no longer pink in the middle.

Pesto Mayo Time
5

Meanwhile, in a small bowl, combine the pesto and mayo (see pantry for amount). Set aside for later.

Whe chicken has around 5 mins remaining, return the (now empty) pan on medium-high heat with a drizzle of oil.

Once hot, add the leek and season with salt and pepper. Cook the leek until softened, 3-4 mins, stirring occasionally.

Once starting to soften, add the peas and stir-fry, 2-3 mins more. Then remove from the heat stir in the butter (see pantry for amount) until melted. Cover to keep warm. 

In a small bowl, combine the pesto and mayo (see pantry for amount). Set aside.

Serve Up
6

When everything's ready, add the red onion to the leek and pea pan and toss to combine.

Share the roasted potatoes and veg between your bowls. Top with the chicken.

Dollop on the pesto mayo and crumble over the Greek style salad cheese to finish.
